I've gone overboard over the years collecting pedals. I have started to sell some over the last year and since getting the Helix I've started to sell pedals that I never thought I would sell because the Helix sounds so good and it's really all I need. That said there are still pedals that I really like a lot and wouldn't sell. I really like my collection of all the HT Blackstar pedals, they sound brilliant. I have a couple of Damage Control tube distortion / preamp pedals and I really love them. I really like my ZVez Box Of Metal, I don't think I'd part with that. There are others as well but these are the first ones that spring to mind as keepers.
