Serena Williams, at times, has been as dominant as any player I've ever seen in tennis - maybe not Barry Bonds 2001-04, but pretty close to it.
To put all of this another way, I think with greatness you have to consider different time spans.
- Ultimate peak - how good a player was at their very best, over short periods of time.
- Peak years - how good a player was during their best years, over a few years at least.
- Career- how good a player was over the course of their entire career.
In looking at overall greatness, all three must be weighed with somewhat equal measure. It also separates the different tiers of greats, so that we have players like Navratilova, Graf, Court, and Evert standing tall in all three categories, but Serena--and more so Seles--falling a bit short on the last, at least relative to the Big Four. But I think you can say that Serena's "ultimate peak" is as high as anyone's, perhaps higher. Seles is close, and her short peak was up there with anyone.
I'd respectfully disagree with that and the levels of domination. We discussed earlier Monica's dominance in the 91/92 period and we've discussed the other greats and comparative dominance. If we're talking ultimate dominance over a couple of years then Navratilova and Graf have the best records.
Here is a comparison of Graf, Navratilova, Seles, Serena and their best two year stint.

Serena's best years fall some way short of the others. In fact Serena's highest win/loss percentage in one year was last year (94%). Graf and Navratilova both equalled or bettered that 5 times.
I would agree though that Serena, at her very very best maybe the "best" player I've ever seen. Note "best" as different to "greatest" which I really relate to accomplishments and overall dominance.
I'd suggest Graf's 88/89 or Nav's 83/84 combos were the best of those, with Monica's 91/92 seasons following.
