whats the climate you are in? are you stuck in snowstorms while working at the door? then a plastic body light would be best.
but of those 2 i still would vote for e20.
why 2AA light? so you can use it as kubaton /fistload?
looking for longer runtime than 1aa?
as modern 1aa lights will suprise you with their brightness.
might not run that long but more convinient size to carry in your pocket.
do you need that Zoom feature?
and you want simple on/off light without other lightoutput modes?
if zoom is not important,
simple 2 mode light option would also be eagletac p100a2

i have no experience with it but many here say its good. and pricing is sill ok at 43$
if you are not carrying it in your pocket.. but mostly keeping it at a desk or sorts but do work in freezing doorway (hated that myself) fenix tk20 might be an option too.. still 2aa light but lot heavyer and bigger than others above, but has rubber handle and warmer led tint.
and dont forget you do get 8% off the price at 4sevens.com by using cpf discount code. (fenix store is basically same firm)
the same discount also works at eagletacstore too i believe?
