I typed out a huge reply complaining about Razer and then deleted it and tried another, shorter, reply which I also deleted and tried walking away from this thread. To make it briefest, don't buy Razer. They don't support Linux. Their windows software sucks a ton anyway.
I've used my Razer hardware with the Steam Deck and Dock like a sort-of laptop and it all works out of the box but LEDs sit on demo mode since there is no software to change them. You can't change anything in fact so any macro keys are useless too. The selling point for me was customizability which isn't there on Linux. Don't quote me on that I know how absolutely stupid it sounds in any other context.
I bought all my Razer peripherals before they even announced the Steam Deck. The software has gotten worse and a newer version bricks a gamepad I like to use as a media controller from the couch. If I had to replace anything I would definitely go with any other brand now. I don't see that happening any time soon though because the Deck does most if not all of the work in games now.
Sorry about having no recommendations in this reply. I have a bone to pick with Razer today. Synapse shit the bed mid episode last night and my media controller gamepad bricked out for a few hours. I recommend staying away from Razer for your sanity. Also don't waste money on features not accessible on Linux.
My neighbor growing up who still lives with his parents and doesn't drive has all his rent and car money spent on his computer. I have his old graphics card and it doesn't struggle with anything I throw at it. I think he uses Steelseries. I trust his judgement more than mine. Steelseries probably holds up to a lot of wear and tear or else the guy wouldn't be wearing them out and getting new ones.
