IIRC, you only need to rotate the PCB in the LS-32(-01) if you mount it “wrong” - I’m pretty sure that the SS mounting plate can be mounted into the TE either horizontally or vertically. It’s been a couple weeks since I last had the LS-32 in, there’s a very fair chance I just totally blacked out when I was installing it and ended up with no memory of PCB rotation.
The LS-56(-01), on the other hand, definitely needs to be rotated, since the MS can only be mounted “vertically” (i.e., screwed in the top and bottom rather than the left and right). It’s a simple procedure, especially if you’re already swapping out the stock square gate for the octogate (best part about the LS-56 imho) - though the screws you need to take off are typically screwed in ridiculously tight at the factory.
Since the LS-55(-01) uses the same mounting plate, the same applies for it.
The GN pushbuttons feel great, a lot more crisp than the Sanwas. I have mixed feelings about the KN buttons, though. They make for great stick art, but the clear plungers have a very cheap feel to them - they combine the vaguely mushy, “inconsequential” feel of Sanwas with the mash-difficulty of Seimitsus, so it’s a worst-of-both-worlds sorta situation. The same goes for GNs with clear plungers.
I guess it’s possible that I’m just imagining things, but I swear the set of GNs I installed in someone else’s stick have a better feel to them than the KNs in mine.
