I have a hhkb type s stock, regular hhkb lubed and silenced, and a novatouch lubed, silenced, o-ringed, and with gmk keycaps. (Both are silenced with Hypersphere's foam rings)
In order of most quiet to least quiet: novatouch, regular hhkb, and finally type s.
However, order of most tactile to least tactile: type s, regular hhkb, novatouch.
All three are pleasant in their own way to the point that I can't actually pick a favorite.
And yes... the novatouch modded well feels amazing.
I will open up the type s and lube it at some point and then re-evaluate.
