I was a long time user of the original HC-110 and still have some here. But I switched to PMK Pyro and Pyrocat-HDC and never looked back. Pyrocat does everything HC-110 did better and cheaper. For some edge cases, I still use D-76, DK-50, and D-23, but that's fairly rare.
HC-110 - it is rumored - was created for high volume photo processing shops as a drop in replacement for D-76. For the volumes any of us likely use, it makes no sense to keep chasing what is now a largely defunct formula. Pyrocat will give you comparable acutance, well managed highlights, somewhat better effective EI, and better grain masking.
I see, well, I do still have some powder packs, among them, Micopen, SuperProdol (meant for my deep-frozen Neopan 400 and Neopan1600), and D-76, heck, I even think I have a pack of XTol lying around, though, I have no idea about the condition on these, as they are probably around 10 years old now.

Well packed dry chems tend to hold up a bit longer at least, I will mix the XTol at some point and to a strip-test to see if there is still some reaction in the chemicals.
I actually think that I might have pyro too, I have to check (I thought I purchased some to have, back in the day, but never got around to use it).
The thing with my typical developers though, is that they are long lasting, first and foremost, so 95% of everything is developed in either HC-110 and Rodinal.
I use HC-110 for a different and possibly cleaner look than Rodinal, but, for films like Acros, Rodinal 1:50 just gives it bite, grit and a wonderful contrast.
If I was to use a 1 litre pack of D-76 for example, I would normally shoot 8-10 rolls and run them through the dev and then dump it, because I would have no chance to use it again before it went bad.
So for me, it is really about having something on hand/on demand that will just work well, I do have Ilfords Ilfotec HC in an unopened bottle ready to go now, but I still have about 250ml, left of the old-type HC-110 that I will finish first.
I shoot very little generally, and about 60% of everything is digi*, the rest is analog, but then split between HC-110 and Rodinal, so I "burn through" my chemicals at a snails pace. (I do portraiture)
Winter is an even slower time of the year, as it is usually meant to be the darkroom-season to make some nice prints from the developed negatives made over the summer.
- incidentally, I swear to Ethol LPD for printing, as it is powder (well, it used to be!
