I sold my Mythos and got an SPII just before Christmas. There’s a blog post pending on it but in the meantime:
The Anfim is really loud compared to the Mythos. Might not be an issue in a big shop but mine is pretty small and every time we grind a dose it’s really noticeable
The clump crusher on the Anfim is made of metal so won’t wear out and need replacing like the one on the Mythos
Takes about 5 secs to grind an 18g dose. Delivery into the pf is beautiful.
The Anfim has barista mode, which my Mythos didn’t, so topping up doses is really easy in comparison to flicking through the dosing presets on the Mythos
Adjusting the time isn’t so easy on the Anfim - you. Need to long press buttons, and then the first option to adjust is the whole seconds, when you really just want to take 0.1 or 0.2 off. The screen is slightly awkward to view compared to the Mythos, but you only need to look at it when adjusting anyway
Grind adjustment is by worm drive so it’s super super fine. Doesn’t need much adjustment during service - sometimes with the Mythos I found if we were getting slammed it would get really hot and we’d have to go finer and finer, then back off once things calmed down.
The spout comes off with two Allen bolts for cleaning so it’s really quick to give it a decent clean - Mythos is pretty good in this regard too though.
The Anfim retains about 10g between the burrs and the spout which is higher than the Mythos. Worth considering depending on what sort of volume you’re doing.
The cooling on the Anfim seems really great.
In terms of taste and extraction there’s not much in it - you can push both pretty hard and get good tasting brews.
