TL-2 beam is splotchier (more like spider-webby) than the nearly-perfect E2e beam. On my sample, my TL-2 out-throws my E2e by much more than the 10% number from JohnK's post.
Overall, the main reason to get the E2e is that it's got the smallest size, best machining, best switch by far, and best overall beam quality (which does not translate to best throw). Negatives for the E2e are that it's expensive to buy, replacement bulbs are relatively expensive, and if you want throw it's not the best (though I think the beam is tremendously useful as-is).
TL-2's advantages over E2e are that it's much less expensive, not much bigger than the E2e, replacement bulbs are very cheap, extra bulb on board. If you want throw, TL-2 beats E2e, but you give up beam smoothness (if you care about such things; many people don't).
TL-2's advantage over something like the PM-6 is that the TL-2 is a good deal smaller.
In summary, TL-2 is, IMO, best combination of not-too-expensive, reasonable quality, small size. E2e is my fave for small-size best-at-any-price. You'd go to PM-6 if you were focused on throw and didn't mind a bigger heavier light.
