MG75V2

The firmware used in PCB is provided by solution provider (mostly), spark link in this case. So I doubt there is much difference between IROK firmware and SU75 Pro. (maybe older vs newer firmware could make a difference) Anyways I will suggest MG75v2

it's sparklink PCB* not IROK (IROK uses sparklink for their MG series). You can get keyboard from any company which uses sparklink PCB, it's just that IROK is cheap and accessible.And its not about durability but about performance, hardware and software/firmware. Only the newer MG series (like MG75v

none will. MG75v2 does not use spark link but more like clone (or could be even stolen) spark link Gemini solution, and it performs as good as/better than the real Gemini solution. It uses the same hardware and maybe even very similar firmware but it isn't made by spark link.It uses the same solutio

MG75v2 is quite good but the software is a bit worse. Irok didn't use Sparklink, it's their first board using their own software and MCU I think. Missing some features like profile switching hotkeys etc. Top tier 75%. MG75max is very nice, just uses sparklink web driver and it's very good price/perf

Cant tell unless you get one. I am also waiting for my HE keyboard to arrive because i feel like my keyboard is not responding fast enough when doing quick combos input. Get a good quality keyboard that is affordable and have good firmware+ pcb like keyverse st63, AE68/64 pro , some of the irok like

Make sure you've updated your MG75V2 to the latest 1.20 firware (https://www.irok.cn/news/77), it fixes latency related bugs and adds quick profile switch bind.
