Intuitive is better in my opinion but it seems to promote more cube rotations.
lolwut?
No. Your intuition must suck, then, because the whole point of intuitive F2L, is so that you can use intuition to insert the pairs. And if you can only insert it with one hand, then you're doing it wrong. In fact, most people who learn alg F2L, get used to one set of algs per case, and then have to rely on cube rotation, to set up the case.
In other words, what you said is completely backwards. Intuitive F2L actually promotes LESS cube rotations.
I hate using B turns if the pair is on the back though.
People use B turns during F2L?
And to TC, I use intuitive F2L, except for about 4 cases, which I used optimal algs for. I can insert with both left and right hands, for half the amount of cube rotations. Doing it intuitively means you actually understand what's going on, and can adapt to any changes in the situation. To me, that's what makes intuitive better.
Choosing between one and the other is foolish, in my opinion. Getting best of both worlds is where it's at.
I'm also sub-20, and the intuitive F2L is what is getting me faster and faster.
