To highlight the obvious from just the few posts in this thread: These lights are very personal, and one man's favorite will be another man's POS.
A lot has to do with ergonomics and a light's features that fit an individual's purpose better than another individual's purpose.
For my part, I like and use my E1L more often than my L1 because my personal preference is for the smaller light which is obviously the opposite of Size15's preference.
Neither of us is "right" or "wrong"; we just have different preferences.
I also find that, for my "personal" purposes, the low of the E1L is more than enough most of the time, so in my case, I enjoy some pretty remarkable runtimes with it.
So while I know the original poster appreciates all comments and suggestions, be aware that, as they say, "Your mileage may vary".
Take everyone's comments as they are, but don't accept that another's preference will end up being your own.
I should know; a good handful of the lights I have were bought at someone else's suggestion, but once I actually used them, I found that I didn't like them much at all (even though they are fine lights in their own right).
Just a bunch of .02 worth of writings... and worth every penny.
