I have the velcro system on my Diva LX, has about 50 dives on it. I haven't had any problems with them on my personally cared for velcro.
When renting a QD, I lost a pocket when being helped to my feet on a washing machine rocky exit. IMHO, any quick release system is not going to be ideal where there is significantly greater risk of the front of your BC being bumped or snagged. You must be conscious of this failure point and plan accordingly -- this may mean reverting back to the standby weight belt in certain situations.
I like the WI BCs (over a non-WI BC), but I do split up my weight between a light weight belt, some in the pockets, and some on my back (either steel tank, or in the trim pouches).
The new Surelocks have material in the "where the pocket gets inserted into the BC" area that keeps this area expanded so it's easier to put the weight pocket into position. Nice feature, but with the velcro system, the pocket area of the BC flattens out when not using pockets. This gives me the option of using the pockets, or putting my weight on a (more secure) weight belt.
