I like razer chroma tournament edition and G410 Atlas Spectrum, both are similar with the rgb function,but at the same time some things are different then the other. And whats a good gaming mouse with or without rgb
I would personally stay away from Razer keyboard as they use cheap mechanical switches, they're not as reliable as the Cherry variant of switches. Take a look at the Ducky Shine 5, it's not openly available at the moment since it's brand new and it's not tenkeyless but it's quite small and one of the best RGB keyboards out there.
Corsair K65. This one uses Cherry MX red switches. I personally prefer brown switches
The one I'm using is a K70 (has 10 key) with brown switches and it's hands down the best keyboard I've ever used.
I will happily recommend almost anything except corsair. I have reasons it involves customer support and RMAs, I'll not get into it here.
Ducky are excellent as above.
The orion spark from Logitech is supposed to be good but RomerG Switches...
I personally don't like LEDs in keyboards unless they are user serviceable, which is none of them unless you custom build. They tend to burn out rather quickly.
What about gaming mouses? because there's a shit ton of them
I'm pretty satisfied with my Steelseries Rival. Very good sensor and switches and you can change the colour of the lights to whatever you want. Only problem is the rubberized sides feel a bit rough and wear over time and it's a bit big and might feel awkward for some people.
I like mionix. I have their Naos 3200 and would replace it all day long with another or a Castor. My brother has the Avior. No complaints from him.
