I'd probably opt for a Fulltone if I wanted either Vibe or Trem. I find getting a decent sounding trem pedal is incredibly difficult. So much so I just opted to buy amps with good trems on them.
Amps will always have the best trem/vib circuits, nothing comes close to those Maggie and Brown/Blonde circuits. Those rare mechanical tremolos also sound very musical.
I'd have a pop at that if I lived the US.
