Well, let me try to contribute.
I really LOVE the Uni-Vibe model in the AXE FX. I do not miss it as a pedal any all. Just play with the depth control, that matters: 5 is light effect, 6 is moderate, and 9 is heavy. Use it before the amp block. Add 1.5 db to it in output. Play with the bulb if you want. I can get some great throbbing Hendrixy/Trower/Doyle Bramhall II UniVibe sounds with no problem.
The Rotary block can be tricky, in some ways, because sometimes we try to emulate other rotary pedals, which is not the same as a REAL rotary Cliff modeled... (I really liked and used the Hughes & Kuttner Rotosphere, great pedal/effect, but it was not exactly like the real thing).
With the Rotary, sometimes you have to play with the mix or wet-dry blend control to dial it in to taste. I do like it after the amp block better than before it, even in mono. Some like to add a dry signal routed around the rotary block (shunt down a row, then back up after rotary block) and then keep the rotary over 75% wet.
The mic spacing control is important if you are playing in mono versus stereo, and the high rotor length has a big effect on the overall tone/sound, so play with that. Yes it would be nice to have some "presets" but it's all in there if you play with it/experiment.
I like the slow leslie sound with speed at around 0.125k myself...the fast leslie sound is best between 6K and 7.2K-ish to my ears. I like to use an expression pedal to sweep between these, with some dampening, to emulate the ramp-up and then set the curve not linear but steep, but flat at beginning and end speed settings if I want to park it there. I think the Rotary sound is one that always perks people's ears up when playing live. And you can get a pretty good Jazz organ sound from our guitar (check out the FX8 preset I designed called Jazz Organ for example).
Good luck!
