That's a pretty wide, open-ended question. You have to decide what it is you want to accomplish with your flying to determine what components to use. It's all a bunch of trade-offs and there is no "perfect" solution. Personal preferences for Speed, Endurance, Handling, Cost, size, durability, flight environment, etc... the list goes on.
What is it you want it to do?
Cheers!
