I have had MX Ergo failing due to switches wearing out after ~3 years of use and several hundred hours of Factorio. Both MX Ergo and M570 share the same D2FC-F-7N switches, so durability should be similar. I've replaced the stock D2FC-F-7N with D2F-01F for over a year and half and it has been working great since.
