I don't think any games have a huge luck factor in the long run. Razz probably has the biggest luck factor of any game.

In terms of skill, nlhe takes the most. This is because you are able to make more plays regarding overbets of the pot. This is especially present preflop while raising from the blinds.

Also, nlhe has the psychology factor that limit games do not. Limit games can be beat by playing a certain way for every situation, every time (rarely mixing it up). NL this not the case.

Postflop there is almost nothing different between plhe and nlhe. The difference is preflop. In nlhe you can massively overbet the pot preflop (something pros and good players postflop don't do). You can also massively overbet it postflop, again something pros don't do.

Example: you are playing a pro heads up. In a pot limit game the pro will win 90% of the time (relative figure). In nl, going all in preflop everyhand significantly reduces those odds. Also, on hands where you flop a draw and the pro flops a set and you go all in, he is hard pressed to call because he knows in the long run he will win more than 25% of the time.
