My biggest complaint with topre. Is how the 45g switches feel different on every board. Also, I don't like gaming on them.
I've owned a fc660c, three hhkbs, Realforce 87u 45g, and the Realforce rgb. I only really enjoyed typing on the fc660c and the 87u, but when I got the 87u I stopped using the fc660c. And I've bought and sold two hhkbs in that time and have kept the Realforce as a daily driver for work. Finally, I was extremely disappointed with the realforce rgb, build construction is a step down from other realforce boards and it did not feel like the my 87u, if this was my first experience with topre, I would have hated the switch.
So really, in the end. I feel the typing experience is different on almost each topre board. Hell, my girlfriend has an 87u, I purchased both on the same day, and it feels different from mine.
