Interesting thread. I guess I'd ask what kind of shooting you'll be doing and what technique you'll be using when changing mags.
For me, I never let my mag just drop to the ground or bench. I let it drop in my hand. Others might be OK just letting their mags drop to the ground, but if it were me, I'd probably add a bumper, like I have on my pistol mags, to be comfortable doing that.
Since I prefer catching my mags, I like the shorter extended mag release (Volquartsen, UTG, shorter Kidd version, etc.), so I can do it one handed. I cup my hand under the mag, and use my ring or little finger to operate the extended mag release, and the mag falls into my palm.
If I tried doing the same thing with the longer wrap around releases (Kidd wrap around, etc.), I'm not sure I could do that one handed. I picture that I'd operate the release with one hand and catch the mag with the other. I could be wrong, and maybe others have a one handed technique that works.
The Crossfire that you mentioned might work one handed, but might require some contortions of your fingers to do so.
On the other hand, if you are going to be doing action shooting, releasing the mag with one hand and inserting the next mag with the other, or using a two hand technique to catch and replace, then the longer releases make a lot of sense.
