In order to operate any suspension you need a datalogger and sensors.
What Ohlins/Ktech/Mupo gives you is wide range of adjustments and ability to change springs. NIX vs FKR have design differences but if you are not within 10seconds of BSB pace, it won't make any difference.
if we want to uncover the can of worms, looking at suspension alone without geometry of the bike is a waste of time.
Having forks at 0mm offset to the top clamp vs 6mm is a huge difference to how front springs work. Obviously its linked to rear shock length and shock linkage.
ps.
Ideally you want to have datalogger/sensors fitted, pay to hire Darren at every track you go to figure out setup and document it.
