Having used a variety of boards over a relatively short period of time, including a Poker, Noppoo and Filco.
I would say yes quality wise it goes Filco > Noppoo > Poker.
However when it comes to use, I found the differences in build quality not really matter, since I didn't think them noticeable, I currently am using a Poker, and I love it, while yes the PCB flexes a little when pulling keycaps from the centre of the board, while just typing I've found no such issues, with either reds or blues (on two different boards)
