Generally Vortex has a really good track record, however since their Poker line is much more popular than their ONE line, you may not hear alot of failures or issues. However of the time I have been researching and reading about mechanical keyboards, I have not really read of any issues with the particular board you have linked. And if you are looking for a backlit board that has Tactile Grey's then that board is pretty much the only one that you can readily buy. So if anything hit the buy button if you are interested in Tactile Grey switches.
Also something to note, If you are easily tired by typing for long periods of time, then I would not really suggest you get Tactile Grey switches. However if you are a heavy handed typist, then go right ahead and enjoy the nice stiffness of Light Greys. Just a friendly suggestion from someone who loves heavier switches
