Here's a chart. It started out as an attempt to quantify just how good Rafa's been on clay relative to other clay players, but then became something larger. Basically, I started with my PEP (Premier Event Points) formula and divided it by "Potential PEP" (PPEP) - meaning, how much PEP a player could have earned. The column "height" represents that - a percentage of total possible PEP. The width represents the total number of PEP earned - meaning, players who played less on a given surface or had shorter careers have narrower columns. For instance, as you see, Novak and Roger on hards are the two widest columns because they earned more PEP on hard surfaces than any other player on a specific surface.
This chart illustrates roughly how dominant different great players were on different surfaces, starting with Rafa on clay (68.1 PPEP%) and ending with Roger on clay (24.2) and everything in-between. I may have missed one or two specialists, but they probably would end up towards the Roger-on-clay end of the spectrum, if they're on the chart at all (e.g. the great clay specialist Thomas Muster was at 18.8 on clay, so didn't make the chart). The columns are color-coded by player, so you can relatively easily find specific players by looking for the same color.
The chart, with some remarks to follow:
(I don't know why it says "Formula Bar" - I took several screenshots and couldn't get rid of it, so just ignore it).
OK, a few thoughts.

- Surface GOAT - This well-illustrates just how dominant Rafa has been on clay, with that huge gap between him and everyone else. Again, this means he won 68.1% of the total possible PEP points on clay. Quite astonishing, really.
- Lendl on Carpet? - I knew Lendl was a maestro on carpet, but this was a bit surprising to see him second. McEnroe actually had a higher carpet peak Elo, but Lendl looks better according to this metric. Borg on clay is right behind him, unsurprisingly.
- All-Surface Greats (ASGs) - Only a handful of players have every surface they played on represented: The Big Three, of course, with Novak being the most balanced (his worst surface is clay, and he's still 19th on this list) - not counting the few carpet matches all three played. Borg has three surfaces in the top 11 and he was still pretty good on his worst surface, hard courts, and still on the chart. Laver has all four surfaces represented, and would probably be more dominant on this chart if I had includes his pre-Open Era stats. Finally, Jimmy Connors - who is one of the most balanced players of the Open Era. His clay record is kind of forgotten, but he was really good on clay - about as good as Vilas and Federer.
- Just missed the "ASG" mark) - Lendl on grass (19.5) isn't that far off, McEnroe on clay (12.8) is well off, Rosewall on carpet (23.2) and hards (20.8) is close. John Newcombe is another balanced player who was good on all surfaces (18.2 or higher), but only shows up on one surface (grass at 30.7).
- Weak Surfaces for Greats - you don't see it on the chart because it ends with 24.2, but the worst surface performance by ATGs are: Sampras on clay (6.3), Edberg on clay (7.6), Ashe on clay (7.9), and Becker on clay (9.5). In other words, all clay and three of four playing in the 80s-90s. Next up would be McEnroe and Murray (12.8) both on clay.
- Comparing across surfaces - My favorite part of this chart is how you can compare across not only eras but surfaces. This chart tells us that Nadal and Connors were about as good on hard courts (though Nadal played a lot more), or that McEnroe was about as good on carpet--his best surface--as Sampras and Federer were on grass, their best surfaces. Or that Nadal was about as good on grass and hards as Andy Murray was on his best surface, grass. Or that Borg on clay, in his short career, was a bit better than Roger or Novak on any surface (though Borg gets the benefit of his numbers not being softened by decline).
