from someone that has actually used both, just my opinion, but having a hopper doesn't make the process any faster. it is just a hopper you need to fill up with possible bridging issues depending on the brass being annealed. hopper or not, if it takes for example 6 seconds to anneal XYZ brass, it still takes 6 seconds regardless if it has a hopper or not....
by the time i swap out parts and fill up the hopper I'm already a 1/4 of the way into annealing with the EP 2.0 annealer as it will adjust from 5.7x28 to 50bmg (even 20 vulcan), rim or no rim, and adjust in less than 30 seconds without having to add or remove any parts...
If you need to pick up the brass, manually orientate the brass in a particular direction, and feed either a hopper or single feed fence, then it really doesn't matter IMO and it is just a hopper you need to fill up and you still need to watch the process while an open flame is running (not like you can just go mow the yard and come back with an open flame)..... You're still feeding the machine... now if you had a case feeder (not a hoppper) that does all of the work for you, then that would be a whole different story but a case feeder = a lot more money and is really not needed when average anneal with most flame based annealers takes ~6 seconds x100pcs = 600seconds / 60seconds = 10min per 100pcs = drop in the bucket for the reloading process... EP 2.0 is based in the KISS method for sure and has everything you need to anneal right out of the box other than the propane tank.
