Can't speak on the release other than I know most people that try seem to like it. For a strap go with a buckle. Quieter, quicker and more consistent.
I have the WiseGuy and have used it the last five years. Great release. My groups really closed up when I started to use it. Great trigger, nice and smooth. I can't say that I find it noisy in the field with the velcro. Once I have it on, it makes no noise, and I know where the strap needs to end when I pull it through the buckle part. If I do need to readjust, I just hold it against me and that can really quiet it down when opening up the velcro. I hardly ever have to do that though.
