Went to my rehearsal studio to do some bass and fuzz pedal comparisons at high volume.
Note, the graphic on my custom fuzz pedal, pictured below, may be considered NSFW. If you have an issue with it, please PM me directly rather than reporting me to the mods over it and I'll take it down.
All my electrics in one place at one time for once:

These three are tuned BEAD:

Did a comparison of fuzz pedals as well. Since all of them are Muff based, I decided to take a "family photo":

Conclusions:
My 4003S is my most aggressive sounding bass. The 1975 4001 (the blue one) sounds similar, but still different (note, I have a modern 4003 bridge pickup, reissue toaster neck pickup, and wiring harness in the 4001). Maybe it's because it has older strings and is in EADG?
The T-bird in series mode doesn't sound that different, but I need to bump the highs on the amp a little to get it really close.
As far as the fuzz pedals, my custom Dunwich still sounds the best to my ears, partly because it can be tweaked the most. Besides the usual volume/tone/sustain controls, there is also a mids knob (that's nearly dimed), a "crunch" knob like with the Swollen Pickle, a switch between traditional somewhat scooped mids (the circuit is based on the Green Russian, so not as scooped as the original Big Muff) and flat/boosted mids, and a switch between LED and Silicon diodes (pictured here in LED setting). Switched to traditional mid voicing and silicon diodes, the sound is similar to the EHX Green Russian reissue. Switched to prominent mids and LED, of course, it's a much nastier beast. I'll probably be getting a second one with more "family friendly" art, possibly of a Tu-95 bomber (since that's what it sounds like).
The Way Huge Swollen Pickle was the main fuzz I used for a while, though it actually belongs to Catapult's lead vocalist. Way more low bass and high mids than my custom Dunwich or the EHX Green Russian. I remembered why I stopped using it... a bit too glitchy in the lows for my tastes (though that may be exactly what some are looking for). A lot more low end than any of the others though.
Least usable for me was, no surprise, the regular big box Big Muff. Too scooped and too glitchy, not enough attack. There was a reason I only used it in conjunction with wah when I had it on my board.
In a less dense mix than Catapult, the Green Russian reissue would be really good. I'll be keeping this and possibly starting a second, smaller board with it. Not glitchy, very solid in the lows and with enough low mids that it would probably still be heard in a mix. Even sounded good at low distortion settings. Would definitely recommend. Definitely way more attack than the regular Big Muff as well. Well done, EHX.
