Having 2 systems is much difficult to maintain/upgrade. But have you at least tried cables from 1 system in the other, to see if you’ve got the better match going, or to help hone in on a favorite brand/model?
I see you’ve got AQ cabling in the 2nd system. I’ve done a lot of AQ upgrades over time. Their line scales very nicely; huge price cliff when you get to the silver cables, though. I recently upgraded my girlfriend’s system from Rocket 44 to Rocket 88 (latest version, not the older braid) and thought it was a very nice improvement, worth the cash. I’d also guess the jump from Mackenzie to a Water would be a nice move - judging by my upgrades though analogous models of their prior IC line. AQ improves their cables over time, and a current Water (2nd from top copper) will compete on par with the Cheetah (PSS silver; was positioned 1 level above their top copper at the time) from two lines prior. Mackenzie would be analogous to the Diamondback model from back then. Not to mention the build quality of the old line pales compared to the new stuff.
