I use both, at different times, for different things.

I know some find this hard to believe, but a converted Polaroid is smaller, faster, lighter, and has vastly superior vertical-orientation shooting ability over your garden variety Speed/Crown.

One of these days I'll grab an old 90mm, a tiny one, and get it put on a 900 model I picked up from a friend for $25 (unless Ben finishes up his project first). With that and my 135mm model I'd be set for most anything I'd want to shoot out in the wild. I could fit both cameras and enough holders for any outing in a small messenger bag.
