I' say strike bezels have one very particular purpose. If you don't foresee having any use for it, I wouldn't bother with it.
I can't say I've ever actually had a problem with putting a light down while it was still on, so the that's not really much of a benefit of the strike bezel for me.
The protection offered by the standard, smooth bezel has always seemed sufficient to me. Not so much as a scratch on any of my 6Ps, and anything that could really damage a 6P with the regular bezel would damage a strike bezel version just the same, in my opinion. It's not offering much protection at all.
So for me, that just leaves the problems of tearing up pockets, being uncomfortable to remove from a pocket, adding length to the light etc.
That said, I do own at least 4 6PDs...
