jj's are ok and generic a little brittle but work surprisingly well for some modules like the Recto style modules. tung sol are nice and chimy for cleans. EH have more fidelity but extremely inconsistent if you don't order matched and specify low, mid, or high gain. The EH have thicker low end but are a little blah at times. Ruby12ax7AC5 HG and HG +have great high gain, nice balanced mids, nice sizzle, unoffending highs. I like these in anything Marshall-ish or super high gain. However if they are super high gain it might make things too over the top and sterile in some modules. I have recently found that a Ruby in V1 with a high gain Mullard Reissue in V2 adds back warmth and some spongyness yet rips your face off if needed. Spend a few bucks and a buy a couple Rubys, a Mullard, 2 high gain EH, and a couple cheap tung sols for your clean and do some comparisons. it's worth it to find what you like. I'm guessing your Camerock will love the Ruby Mullard combo.
One other tube is the Ruby 12ax7AC7 HG, a little woodier more vintage vibe vs the AC5. Might be nice in the Quickmod.
