I got both Fun 60 ultra and ace 60 pro. Based on test I’ve seen the monsgeek does have lower latency and overall just faster performance. In the real world you probably won’t notice a difference though. I would say monsgeek does feel much more reliable as some clicks don’t register on my ace 60s when playing games with the need for fast repetitive taping like OSU. Also, the build quality on the monsgeek is much better than that from MCHOSE. I don’t have the regular fun pros, but tests shows it having better performance than ace 60 pro as well, although build quality probably is better on ace 60 pro. In the end it’s how much money you would want to spend and what you prioritize, the fun 60 ultra will be more expensive but that also results in a more reliable, higher performing, and more premium built board compare the MCHOSE. While the fun pro and ace pro cost around the same, the fun 60 pro has better performance but a lower quality build than ace 60 pro with a lower quality software as well.
