Being good at a variety of styles CAN mean you are better than a player who is VERY good at one style. It just depends how you weight the criteria and how good each person is.
Being a jack of all trades certainly shows versatility and different types of ability....but you may not be the best at any single type, and there lies your weakness.
On the other hand, perhaps wacicha is the best classic/escalating/terminator player there is, and maybe he isn't as good at the other settings (this is all just an example).....however if he is MUCH better than everyone else at his settings than perhaps he could still be considered a better player than the jack of all trades.
Like I said, it all depends on how you weight the criteria.
For me personally, I seem to make most of my points from freestyle escalating games. That also happens to be my favorite setting because it actually provides a thrill of possibly being interrupted, and each second can be more crucial than sequential games. I also like the fact that with good strategy and a little luck you can almost always come back and take a win, no matter how dysmal your position was. That is often not true in sequential games and almost never true in flat rate/no cards.
Anyway, I love them so that is what I prefer to play
