Keep in mind, the BP crown (including Express Tech fans) tend to be a KISS (Keep it Simple Stupid) crowd. The beauty of the systems is they are very simple and rugged. You can add what you really want (weight systems, pockets, etc...) to your specific needs. What you really want/need should be a relatively small list (mine is down to a couple of D rings for cutting tool, light and an SMB bungied next to the tank). Its not so much being beginner friendly in operation(they are), but that you have choices to make when configuring it. This overwhelms new divers.
On the opposite end you have the full on weight integrated BCD's. I will take my Zeagle Range for example. Out of the box it has everything you could need. Weight integration (4 pockets, 50lbs capacity), 2 side pockets, front roll down pocket, 2 zipper connectors for options like pony carriers and more pockets, enough D-rings to outfit a squad, 3 pull dumps, etc..... It's a very nicely built BCD with everything you could ever want. The problem of course is you have to carry everything you could ever want. Having gigantic weight pockets forces them to have a gigantic wing to float the weight, which taco's and induces drag. It was a nightmare to travel with.
