I've never used a gravity feed AB so I don't know if I'd like it or not.
However, my Badger 155 has a bottom feed and a side cup (both suction).
I allways used my bottom jar with my old Badger 250 so I expected that was the way I'd go with the Anthem, and would probably never use the side cup......
I tried the side cup once - and have not used the bottom jars since, so going by that I suspect I'd get on very well with gravity feed
