I'd have to disagree with this, I have mechanical blues that are knockoffs of knockoffs and they are absolutely amazing. Cherry blue is the regular brand otemus are the knockoff I have otellos and they're so obscure they don't even have a wiki page I've already used them for 4 years. The only problem I had with em was that the space bar made a lot of squeaking noises out of the box so I oiled it a bit and now it's the best keyboard I've ever used. It was 25 bucks has multi colored and programmed leds and is full size. The switches definitely seem like they'll last a million strokes or more and I quite like the clickiness of the blue switch.

I wouldn't buy anything less than 100 percent keyboard because I actually like having function keys a numpad and arrow keys. Just look for the features you like in the switch, if it's compatible with cherry stems your keycap options become really good but it's not absolutely necessary if you don't plan on ever changing them. They make soldering not required swappable switch boards too now and while I haven't tried em I heard they're not bad.

So imo depends what features you want and how much bang for your buck you want. If you want ultra luxury high end though can't beat topre switches if you just want a good mechanical switch get whatever.
