Used to find Shimano indefinite and was endlessly adjusting tension, but that was Deore shifters with SLX Shadow mech, which was horrible. SRAM X9/X0 have been lovely. Click, clunk, done. Rapid shift up 3 at a time is also spot on each time. Never fiddling with tension really.
Cables are universal, so long as you use SP41 outer and some SS inner, no matter what brand mech/shifter you use, all with be fine.
Only times I’ve had issues is with rubbish outers and poor quality ferules and the end frays, crud gets in there and then constantly adjusting tension to compensate, but the problem is the cable.
