Soviet Biggest bang for your buck research wise.

[Aurelius]

Based on previous and recent events, I'd have to say that RS research can be much better than that of RBs. Longer write ups than RBs unless you get a combat RB which can be a long write up. For your money, finding a combat write up RB is expensive and hard to find in comparison to RSs. This is but my personal opinion.
