Well quite honestly Hasbro is the best for Star Wars. They do have their 6" collector oriented line which is overall quite good for the price. Japanese import manufacturers like the Bandai SH Figuarts and others are typically going to be better figures but cost a lot more, are the same size, and have a very limited number of characters. Though the Japanese are somehow doing a Mace Windu and Grievous before Hasbro which is odd but then again I don't think those companies will ever move on to doing the different background characters like Hasbro already has. So for stuff in the 6" department you have some choices and if you like the way one company did a character better than the other then you can always mix them together in a display. For a basic review:
Hasbro - Pros: low retail price, character variety, good articulation, endurance. Cons: less than great likeness to actors, some harder to get than others.
Japanese imports - Pros: higher detail, good articulation. Cons: pricier, less character variety.

Hot Toys are probably the best but they are more like mannequins you set in a pose and leave them be. You can't really play with them or try to fiddle with them too much because that's not what they're for. I'd say reserve getting a Hot Toys figure for your favorite characters only since they take a bite out of your wallet and then they really just do a damn good job of standing there and looking cool but not a lot else. I also don't think Hot Toys figures really have much of a second market gain since none of them are rare or excessively demanded due to the smaller crowd of patrons.
