Hi Darryl,
I have a Concept 2 Pro-got it last Aug.[a semi-emergency purchase- my old BC developed a problem immediately before I was leaving for a trip] I have done 21 dives with it (one trip -warm water). I like it a lot. I find it very comfortable and easy to use. It is similar to the Ranger in design and lift capacity, and has the same power inflator. It is, of course, back buoyancy and weight integrated-with the same weight ditching mechanism ("ripcord"?) as the Ranger. There are "trim weight" pockets attached to the tank strap.(The lower one of 2 straps).
It has several differences when compared to the Ranger: It has no pockets, but Zeagle makes some that can be attached in several ways (optional,of course). It is made of a nonballistic nylon, and is a less"tech oriented" than the Ranger-fewer D rings, plastic(?) D rings-and it can't be used with double tanks.
Some of these differences may be of no importance,or of major importance,depending on future dive plans.
Zeagle's website has a more detailed description of both BCs,and several others-including one specially designed for women divers-I believe its name is "Zena",or something like that.
hope this has been helpful, and let us know what you decide,
good luck,
Mike
