Hello flashlight community!

I've been mulling over for some time now between these 2 lights. I haven't really seen much discussion or comparison between these two. Is the buck driver really that much better?

What I like about the E12C is the waterproof rating and the redesign. It is also a little cheaper.

The E12R has the buck driver which everyone really likes, but I have no experience with it.

They both function as a powerbank which I think is really cool. The E12C has 3 amps output vs 2 amps of the E12R.

Does anyone have any experience with these lights or anyone who would like to chime in?
