I simply stopped buying consumer grade routers that is supported for 6 weeks and then using custom firmware like WRT to make it stable and give me the features that I needed. I just bought a decent router - TPLink Omada ER605 - part of their prosumer range - stable - UI is easy and it can do LTE switchover and handle multiple types of VPN's.
