I have carried a Surefire EB1 with the "tactical" switch for several years and have been very pleased with it. It is very easy for me to carry in kahkis, dress pants, or jeans and doesn't interfere with the use of the pocket. It also doesn't fall out. Battery life is also excellent. I can also easily use the light with a handgun. If I were to lose/break this one I would buy another just like it.
I initially purchased the Surfire LX2 but I found the light to be too large (both length and diameter) to easily carry. I also prefer the ergos of the EB1. Plus the LX2 pocket clip would break every few weeks. I was not HALO dropping into Durkistan, the dang thing would just break in the same place from everyday use, mostly from getting sprung by the seatbelt. Surefire would send a replacement clip for free but it was really annoying.
I also have an EL Outdoorsman and I much prefer the EB1 as the EL was difficult to carry in pocket.
I also prefer the "tactical" switch to the "clicky" switch.
I'm not a flashlight nut like some and haven't tried every light made but based on my experience I cannot recommend the EB1 enough. Here's mine:
