My initial response: That's about right! You've been paying attn.! I'm not only impressed, I'm flattered!
I'll fill in the blanks
OTOH here:
1.
Djokovic - Obvious GOAT w/ all the #'s in his favor (24 Majors, 40 Masters, 8 YE #1's, 7 YEC's, 428 Wks. @#1, & OGM
2.
Borg - The man owned the early Pro Era taking lead w/ 11 Majors
3. Federer; when he was young & not wussing out against Nadal
4. Sampras deserves respect for his time! He initially took the overall lead w/14 in Majors held by Emerson's 12 (mostly Am. Majors)
5. Nadal can't be overlooked; even w/ his limitations (22 Majors)
6. Agassi gets a nod even though quite a few seasons of waste over 20 yrs! The 1st "Career GS" w/ OGM
7.Connors w/ his body of work over 20 yrs on the tour (109 Titles)
8. McEnroe w/ a few magnificents yrs. of excellence
9. Lendl S/B ahead of McEnroe & Connors w/ 8 Majors, but never pulled off that Wimbledon he treasured so much
10. A few players have the potential to make the list, but haven't done enuf yet: Alcaraz, Sinner. etc.

Well, even though I love stats and charts, I still struggle to settle on a specific ranking - mostly because I can never decide how to balance peak and overall career accomplishments.
There's also the problem of Rod Laver and the Open Era. I think he's got about as good a claim to GOAT status and Djokovic, if we consider tennis history as a whole. But then we also have to include Pancho Gonzales, Rosewall, and Tilden, at least - if not Budge, Kramer, Vines, etc...at least in a top 20-30.
"Open Era Only" is easier, and pushes Laver down the list. Still top 20, maybe top 10, but not top 5.
But peak vs. career remains an issue, and no player is more impacted by this than Borg, who is the hardest to rank of any Open Era great. However...you're not going to like this, but even when emphasizing peak, Borg tends to be a bit over-rated, imo. He was great, but were his best two years (1979-80) greater than, say, Lendl's (1986-87)? Or McEnroe's (1981, 84)? Just as Borg tends to be a tad overrated due to the mystique from his early retirement, Lendl tends to be underrated, because of that 8-11 record in Slam finals, but that is largely due to him playing along side more all-time greats in their primes than any other player. Lendl faced late prime Connors and Borg, full prime McEnroe, Edberg, Wilander and Becker; and early prime Agassi and Sampras.
Anyhow, I'd also rank Novak #1 -- for the Open Era, at least. He is, at worst, the first among near equals. Roger and Rafa would be 2a and 2b. I think, all things tolled, they are too close to rank one over the other. Both have their arguments, and both sort of equalize each other. EDIT: After doing my ranking below, I give Roger a tiny edge, because his two or three best years are better than Rafa's best. But again, I see them as close enough to make any edge meaningless.
I'd then rank Borg, McEnroe, Lendl, and Sampras in some order. It isn't as clear as the conventional "Sampras, Borg, Mac, Lendl" ranking that most lists employ. Sampras' weakness on clay and playing much of his peak during a relatively softer era weakens his edge over the others. I know, 14 Slams, but I think Borg and Mac were both better at their best, and Lendl arguably so as well. I'll still give Sampras the slight edge below, but it is closer than mere Slam count implies.
Connors is both clearly behind that group, and clearly ahead of everyone else - at least among Open Era only guys. I'd then insert Laver, for being the best player of the first four years of the Open Era, which included one of the two best season (1969) of the Open Era; but being the best player for four straight years is rather impressive, even if his Open Era career was pretty short.
I'd rank Agassi, Becker, Edberg, and Wilander, in that order, in a group. Agassi gets the edge due to longevity, but I think you could argue that the other three were slightly better during their peaks. To be honest, I think Agassi tends to be a bit overrated. He was a legitimately great player, but his name career more weight than his record. And really, he only had two truly great years: 1995 and 1999. The rest of his career was rather erratic, and he didn't put together a clear strong peak of a few years like those other guys did. Murray is the best of the rest, as befit his career compared to the Big Three.
OK, now Alcaraz and Sinner. Obviously it is too soon to assess them historically, but as of this moment, I'd probably rank them both between Laver and Agassi. Their peaks--especially Sinner's--are closer to the Sampras group than Agassi and the rest, and really to clearly surpass Agassi, they only need another year or two at a similar level. But I'd already them above him. Connors just had to too long of a career not to give him an edge over them, but I have little doubt that they'll eventually surpass him and--at least--join the "purple tier" below.
Here's how I'd sort it all out.
OPEN ERA (only) TOP 20 (color coded by tiers)
- Djokovic
- Federer
- Nadal
- Sampras
- Lendl
- Borg
- McEnroe
- Connors
- Laver
- Sinner
- Alcaraz
- Agassi
- Becker
- Edberg
- Wilander
- Murray
- Vilas
- Newcombe
- Nastase
- Ashe
Things get fuzzy after Vilas, who I think follows Murray. I think you could make an argument for Rosewall or Courier to edge out one of those next three, but I think the next guys--Roddick, Hewitt, Zverev (yes, Zverev), Chang, etc--belong in the 21-30 range.
If we were considering all of tennis history, I'd probably rank Laver #1, then add Tilden, Rosewall, and Gonzales to the top 10, and Budge, Kramer, Vines and maybe Perry to the top 20. I'd consider Kozeluh, Drobny, and Riggs, too. I'd probably avoid players before Tilden and the pro/amateur split in the 1920s, because it is just too hard to compare. But the sport was relatively stable from the mid-20s through 1967, that we have enough continuity to compare Tilden's dominance to say, the dominance of the Big Three.
And to me, that's how such lists should be considered: relative dominance to the era a player played in - not specific statistical metrics, because those change over time.
