We've beaten the "BIS miles != EQM != RDM" to death here, but I think the question is still interesting. "How much value do you put on the elite RDM bonus?"
I'll say the 100% PLT bonus affects my decisions significantly. Taking that EQM is not in question, the 100% is enough to make me buy up to BA WT+, for the jump from 25%+25% to 110%+100%, on RDM valuation alone. That's as a leisure traveller that cheated for status though.
As AA GLD, I would not make that same decision.
