Indian and Thai dishes
In my experience Thai is much easier to cook than Indian, especially with all of the quick pastes and such that you can use.
Making Indian from scratch takes a bit of effort and repetition. And finding a reliable recipe is a bitch. There are obviously endless permutations for how to make any dish but just take a staple Indian dish like butter chicken and start googling for recipes. The differences in preparation are night and day from recipe to recipe. About the only constant is that you need tandoori chicken and tomatoes.
