I have a '63 Vibroverb Reissue.... It is far and above my favorite amp. The thicker cleans combined with bias vary trem. It's just pure tonal heaven for me. I was hoping to score an Ampeg J-20 for a while... but as I come across them they seem to elude my purchase at the last second! I keep hoping to find a real vintage brown or blonde amp when I have cash available. I am seriously considering trying to chase down a nice Tremolux Piggy Back set. It sounds just about the right combo for me... 2x10's, about 35 watts of power and tremolo! But, I will say, for sure, brownface tones are my favorite of all Fender tones.
