Halo Wars was the best RTS I've played to date, on a console. There is also Supreme Commander and Civilization: Revolutions available, although I think the latter is multiplatform. In any case I think you'd find most of the games that you do find "interesting" are likely to be on both consoles. I'd personally go with whichever one is cheaper and get the other one when you have more spare cash available, both offer great and versatile libraries and share plenty-a-games, just some are cheaper on different consoles.
Disconnect and self destruct, one bullet a time.
