Modulate mode is the standout, and several owners keep the pedal for that setting alone
Shimmer turns lush and usable with the tone knob rolled right down
Quick to dial in, with no hidden button combos or manual to keep referring back to

Owners complain about

A minority hear the algorithms as digital or metallic, competent rather than inspiring
Shimmer is abrasive at default settings and needs the tone rolled well back to tame
Too conventional for players who want experimental or heavily washed ambient sounds

— ziganaut on Reddit

“Had the RV-6 at one point, but found it too metallic. All Boss reverbs are like that to my ears though. Modulated is the best algo on the RV-6, but it seriously pales in comparison to Mercury7 modulation.”
