I can't stand Starcraft's outdated control system, scrolling the screen is a pain.
I play Command and Conquer: Red Alert 2 almost daily and still enjoy it. The Westwood games in the C&C series are phenomenal games, with RA2 obviously being my favorite. Certain factions have small advantages depending on what map it is, sure, but that's generally only on large maps.
A lot of RTS games focus too much on defense, but in RA2 you don't win if you don't apply pressure early and often. No building up your base for 5-10 minutes then attacking, more like building up in 3 minutes then attacking. Although there are exceptions, in most cases games are over after around 5 minutes, sometimes 10. I like that.
Currently playing: Uncharted: Drake's Fortune, NBA2k11, Metal Gear Solid, Picross 3d
