Well—I don’t know about OpenRazer (never used it), but I have used OpenRGB for over a year now…works with all of my RGB & I would “vote” to use it because you don’t know what RGB you might use in the next year or so…
That being said…I’m with the -git version of OpenRGB because of some G Skill memory I have…I have had very good luck with the bug report part of OpenRGB…Real helpful & willing to work out problems.
My hardware is a real mixed bag…ROG Z790 Motherboard, DDR5-6400 G Skill Memory, Phanteks Enthoo 719 case, Arctic P14 fans, Logitech G512 Carbon & a Deepcool LS720 SE CPU cooler…So OpenRGB was the only way to go.
