Have you put those Wago connections under strain on a vibration table? I love Wago's but wouldn't consider them a permanent option for high-current connections on a highly vibrating chassis. I can't find any official info about their use in automotive or aviation applications, but it does seem like folks are commonly using them in automotive from various forums.
Wago cage clamp connectors have IEC/EN 60068-2-6 and EN 60947-7-1 certifications for vibration and pull out testing respectively, among others: Laboratory Tests - https://www.wago.com/us/laboratory-tests
If you trust your skills and have the tools, ring terminals will always provide the "best" electrical and mechanical connection. However, someone who doesn't have good tools or much practice is more likely to make a good connection on a Wago terminal. All you have to do is make sure the wire strands are fully inside the connector body and the insulation isn't stripped too far back. Much less room for error.
