My use case is non-LE. About two years ago I went from WML on the nightstand gun to a uniform set of non-WMLs (Surefire 6PX Tacticals) on my nightstand, in my car, and when I conceal carry.
I have generally found it a change for the better. I find a good light handy pretty frequently. I also prefer how my guns handle without them.
That being said, for many years a G17 (G4 and G5) with TLR-1HL was my nightstand gun and I practiced with it as such. Was quite happy with that. I also have 92A1 with X300U-B that is just a wonderfully cool setup.
So I suppose I'm in the "no WML, but I don't feel that strongly about it, just works for me right now" camp.
