I had the Dragon and the Prestige in my rental collection, picked 'em up in summer of '09. I had real troubles with the MRS weight pouches falling out with more than 4-6 pounds in a pouch (they're supposedly able to handle 10-12), especially with newer pouches. The trim pouches in the Prestige are my favorite trim pouches I've ever loaded, the Dragon's trim pouches are a real hassle to load and unload, we ended up putting 3 lbs in each pouch on the Lg and XL models and leaving them there. The trim pouches in the Prestige started ripping out at about a year of heavy use in rental. The zippered pockets are ripping around the zippers with minimal pocket use after about a year and a half.
We just made the switch to the Cressi Start Pro for the rentals, it's a basic BCD with Cressi's pouchless integrated weight system. We like it so far, but I'm not sure about the velcro on the velcro pockets for the long run. I've got some Aquapro 5 models in the shop and they look to be terriffic, I'm only using the XXS size in rental as it's a great size for kids and tiny women. I've got minimal use on these BCDs so far. The Cressi pouchless integrated system on these two models intrigues me, so far no problems whatsoever. Earlier models had narrower weight pockets that managed to wiggle out of their quick release and dump weights. I've no problems with the new ones yet (wider pockets less likely to get out of place I guess), but the gear is new and not softened up. So far so good, a month's heavy use with zero pouch problems, can't say that with other brands I've used.
I had problems with all the Oceanic pouches I'd used in rentals in the past, with the fewest pouch problems with the original tricky to thread pouches that so many people hated. Typically, the plastic backing in them would crack in the middle and then the weight pouches would want to slowly work forward and then dog ear during the dive and hang by the quick release only (to some extent we've been having the dog ear issue with our Mares BCDs once the pouches were older too).
I've seen Seaquest/Aqualung in rentals for a long time with the occasional lost pouch (as you can tell, pouches are my pet peeve) but no major problems over time.
The ScubaPro BCDs look pretty good. My only gripe is some of the pouches are a bit too hard to dump quickly for some people, and on the back inflate models there's little if any easily accessible pockets on some models for suddenly needed extra weight or to put junk picked up off the bottom.
Every BCD out there has it's plusses and minuses.
