I began using the Sherwood Avid BC about eight months ago, and I really like it. The CQR weight system securely holds your weights, yet they are easy to ditch in an emergency (or when diving from a tender and you need to pass up your weights). The weights clip on securely to the vest; when the release handles are pulled, the clips unfasten and the weights come out very smoothly. My previous BC used a velcro system that never felt secure, and I actually had a weight pouch fall out once while diving.
It would be difficult for someone to fasten the weight pouches on their own after the BC was on, but I've never felt a need to gear up that way.
I don't recall the BC's "lift," but I feel like it holds me high and upright on the surface when fully inflated.
I've never worn a back inflation BC, but I also have never noticed the "squeeze" effect I've heard people complain about. However, I rarely have much if any air in my BC while at depth.
I feel streamlined and am easily able to keep a horizontal position while wearing the Avid, even when partially inflated.
On dives where I've had to wait in the water to be picked up, I've enjoyed being able to get up high and upright on the surface.
One of these days, I'd like to try a back-inflation BC; but I'm happy with the vest, and I really like the Avid.
My opinion in a nutshell: The Sherwood Avid is a GREAT vest-style BC for the recreational diver. Then again, I've only worn three or four different types of BC's.
