To be honest, I don't see a huge advantage replacing the beige keys on my AT102W with more beige keys ... And they would look silly on a TP3.
What I miss with ALPS is things like jolly roger modifiers, RGB modifiers, Geek Hack escape, all the trimmings that you can fit to a Cherry keyboard. If GH did an ALPS key, I could have left the black Esc key on that FILCO Zero ;-) (I have no expectation of the green F1-12 even if the thread starter is another Briton who may have actually used Acorns.)
The only full keyset that actually interests me – but only for a black keyboard (i.e. the FILCO Zero 105 that nobody sells) – is that incredible Diablo one. I may get it – I just suck at Costar stabilisers.
The problem for me, fundamentally, is that I want ISO + tenkey, and there just aren't any. I don't use ALPS because the frigging keyboards don't exist. ALPS died a death long before people grudgingly agreed on the Model M layout. Only the AT102W has a Model M layout and the switches suck.
