Tomorrow proof? well maybe but future proof is if I have learned anything in this hobby/sport pretty much an unattainable goal.

First you need to stop thinking in just terms of buying a transmitter, you are buying a system and at a minimum will include matching type receiver(s). Servos for most part can be pretty much any brand. With your stated goals I would definitely stick with the five majors period and think of each in terms of a system.

To most of my folks I recommend Hitec or Futaba and with your goals I would bypass the entry level systems from either and start with in the case of Hitec's system I would go with the midrange Eclipse 7 Pro and if Futaba is your preference I would go with no less than the 7C.

Either are not the cheapest out there but you never mentioned cost and asked for the best and I feel these listed above meet that goal.
