JarateKingThere are a lot of good options: ducky, coolermaster, filco, pok3r, etc. And lots of groupbuy / custom keyboards if you're looking to splurge or DIY some.
Switches are mostly preference so what exactly are you looking for that razer green switches didn't offer? More/less tactile, more/less clicky, etc.?
I really don't know, I don't know much about keyboards rather than give used Green and Blue switches cuz I used Blackwidow and a logic tech one. I liked the blue switches more if that helps
