I would have to say be wary of the E13 lever. It's both over-engineered and half-baked.
If you really want a lever that feels just like a SRAM (and pretty close to Shimano) downshift lever (the big one), from the pivot location to the hard stops for the lever throw it's perfect. Even has the lever angle adjustment like an X0/XX1 shifter. But...
It has things like a custom T25 ~2mm bolt (cool) for a cable clamp that just doesn't hold very well (boo). That is blocked from easy tightening by a plastic cover that "protects" (yay) the end of the cable and housing, but is not watertight so it just traps moisture (nay). It has double row bearings at the pivot, but the lower one is covered by a large (again custom, cool?) T25 bolt that does not seal at all so again just serves to trap moisture that munches the lower bearing (double row boo).
I also find myself using my dropper much more than shifting. So much that I have gloves with a hole worn through the left thumb but not at all on the right thumb. Enough use that I actually noticed less overuse fatigue in my hand after switching to the OneUp with it's upshift lever feel. The unwrap of the thumb and long arcing throw needing to actuate the downshift-type levers literally made my thumb and hand hurt. The shorter radius and shape of the OneUp upshift-type lever gives a more straight "push" of a throw that can be reached without unwrapping the thumb much at all, and the push action reduces leverage on the thumb joints since the base of the hand remains tight to the bar. I think if you try to set it up like a downshift-type lever it's always going to feel bad, but if you try to align it with the location of an upshift lever (maybe just a couple mm closer since it does have more throw than an actual upshift lever), it feels great!
YMMV with various posts, but I think it works great with the cable pull needed (not much if you keep the cable taut with the barrel adjuster) for OneUp posts (of course) and PNW posts.
