I would also consider the company and people behind the products. Personally, I have always found Zeagle to be a first-rate outfit; great service and support. Every time I've needed something they've gone out of their way to take care of me, and often without any charge.
I currently dive the Stiletto, which is the men's version that the LaZer is based on. It's the best BC that I've ever owned. It fits great, has excellent weight integration, zero inherent buoyancy, it's durable, and it travels well. I like back floatation designs better anyway because they generally allow for better trim and have less bulk. I've never been a big fan of the squeeze effect you get from jackets. The only mods are the addition a split sattle strap for more security on surface swims, and trimming-down the slack in all the strap adjusters for a cleaner profile. Zeagle did all the work for free!
Another great thing about Zeagle's systems is that they're all modular. So, if something ever needs to be changed out, just pop-off the old section and pop-on the new one. This also makes for great adjustability. You can mix-n-match different size parts for a custom fit, or better optimize your rig for a particular type of diving. Another plus for me is that Zeagles come with double tank straps, which is just a personal preference.
Hope this helps, and best of luck with your purchase!!!
