Honestly, gaming keyboards are a bit of a farce. A standard keyboard will serve you fine for the most part unless you are a huge MMO player and require loads of macro keys for complex moves.You can't get a gaming keyboard at such low price.
Just buy a normal keyboard and enjoy your games. Gaming keyboards are way more costly and they probably won't make much difference
I personally prefer a mechanical keyboard with backlighting as I play in a dark room for the ambience. However I find the list presented a bit weak. The Tt eSPORTS POSEIDON Z RGB and Logitech G710+ are not listed as options in the sub $150 group and yet are two of the best in that price range.
It's pretty obvious that this "review" and I use that word loosely is more about being a paid infomercial than providing real info for readers. It is sad how far so called "enthusiast" sites have fallen over the years,
