Within 10 minutes I suspect you will get multiple suggestions to try a BP/W or you will die, so I won't repeat that.
I dove with a ranger for about a year (75 dives). It is built very, very well. extremely robust and it also has one of the few integrated weight systems (rip cord) that I am comfortable trusting. It also has lots of features and also options like extra pockets, pony mounts, etc... Scott Zeagle is on SB and stands behind his products. If you really want a fully integrated BCD, look the the Zeagle Stiletto, it is a bit smaller.
That said, I found it too big to travel with. Even though I dive temperate (50F) waters and am a big person, it was more than I needed (45lbs of lift, big wide wing, etc... The pockets were a little hard to work with (typical with many BCD's). I ended up selling it and going with a BP/W, for me the less is more mentality won.
