I like Arista Premium developer.
Freestyle Photographic sells it here in the USA, and it's probably re-badged from something else, but I don't know what. I can do some digging if you are interested.
It's consistent, comes in a liquid and lasts a long time.
I've been using it exclusively for the past year and a half and so far no complaints.
I mostly use Fuji Acros 100 and Ilford HP5 these days.
I dilute it 9-1 and process for 7 minutes.
