As different as you can get.
I previously have owned deCapos and a former colleague owned R2s at the same time. We spent a lot of time working together in front of my speakers or his. Both of us were using primarily vinyl and lowish powered tube amps.
The deCapo has a "laid back" or "polite" tonal balance. Some will find it wonderfully transparent, revealing and musical. Others will find it dull.
The ProAc is more forward and dynamic. Much more energy from the presence region through the high end. Exciting or edgy, depending on who is doing the evaluation.
I don't want to overstate it, because both are good speakers, but they do - IMHO - occupy opposite ends of the "reasonably neutral" tonal spectrum for monitors.
My guess is that most people will strongly prefer one or the other. At the end of the day, I'd personally go with the ProAcs, but they're really not my long term cup of tea, either.
Good Luck
Marty
