I was certified on a jacket BCD but have done all my actual open water diving since with a Stiletto. I looked at the Ranger as well, and liked it, but ended up going with the Stiletto partly I'm sure because of cost at the time. It was also because I was told the Ranger can handle doubles, but when the shop told me that it's more of a one-tank BCD and doubles were a real pain to set up with it, I figured why would I need the extra bells and whistles. However, my dive buddy/close friend regularly dives with a Ranger recreationally and as a DM and loves it. The way he described them was like the Stiletto is a Humvee, and the Ranger is a tank.
Personally, I think it looks big. It's rugged, but I think for most recreational divers it might be overkill unless you really need the lift. He travels fine with his, but in my limited (but still 100+) dives with him, I've been able to do everything he does with his BCD.
I've never taken my BCD in anything other than warm lake water. I haven't had the chance to travel with it yet on a plane, but I've been very happy with my Stiletto. If I were doing it again, I'd probably look at a BP/W but I don't think you need to go that way if you are more comfortable with a ready-made set up. The Stiletto is a good BCD for the absolute beginner, and it's taken me almost from the start through my rescue and Master Scuba Diver level with no problems.
I'm sure I would have loved the Ranger, too, but any concerns I had about the Stiletto not being rugged or powerful enough have been put to rest through my years of diving with it, taking it down to 130 feet, swimming through flooded tree groves in pitch blackness in 60 degree F water, it's been very satisfactory.
I can't speak to how it works in cold water or with dry-suits, but for warm water diving, I think it would serve one's recreational needs well.
