I'm still using 11t on the Khe and lately Federal at least until I get complete fed up with replacing the 7905 bearing on a weekly basis. I have a 12t on the Nankai. The old Suntour has a 12t also.
I had to get the 11t driver from FF for the KHE/fed (both came with 9t). In a way, I woudn't mind if KHE at least made a 12t, but that company just won't. Have they fixed the bearing design flaw? No. but instead, they made the hub female/bolt style which doesn't look to be showing that much success.
With cassette's I stay with Profile, or really I'm using Madera hubs just because they cost the least and still use Profile parts. I also have a choice to use a "real" cassette with cogs instead of overly expensive 1pc drivers. In the cassette type market I wish Odyssey, Primo, Tree and whoever else just pretty much only made shells for the Profile guts to make things better, and easier to find and replace parts.
