Electronic and Monaco equally so I'll refrain from voting.
Monaco released my favourite side project album overall (Music For Pleasure) but Electronic had two superb albums (1 & 3) plus some great b-sides in between. Monaco circa 1997/8 were at the top of their game but began to falter after an average(ish) second album then everything abruptly fizzled out when New Order reformed. Electronic had a fairly consistent run of quality across their career with only Raise The Pressure sounding a bit laboured and overproduced but even it had some great tracks. I'm a big fan of Twisted Tenderness so for me they ended things on a high.
Revenge I always took with a pinch of salt because their album just seemed like an excuse to go gigging rather than make lasting music though the Gun World Porn EP is a hidden gem. State of Shock is one of the finest songs of any side project and the first "classic" of the Hook/Potts partnership. I'm pretty ambivalent towards The Other Two, admittedly they did some good synthpop type stuff but a lot of their material was tough to get really excited about. Super Highways wasn't a bad record though, if you were lucky enough to actually find a copy at the time...
I'd file Bad Lieutenant with Electronic for obvious reasons; it was a decent album but perhaps not as strong as the stuff Bernard did with Marr a decade earlier. I think after a decade of guitar driven tracks the fans were starting to get bored of the lack of variation in that sound. The gigs were great fun though (Paris!).
The only one I really didn't take to was Freebass; the name, the concept, the hype... bits of the EP was listenable but the LP was er, not.
