I read this a couple of years ago. It depends on your view of the important decisions.

1) If the gating factor is the complexity of the important decisions - Limit Hold'em

2) If it's the impact of the important decisions - NL Hold'em

3) If its the frequency of important decisions - High-low declare.

I don't know if I agree with this 100%, but it is an interesting way to view the game.
