The main distinction as far as I understand is tenure / not-tenure, everything else is just window dressing. Is Senior Lecturer when they're awarded tenure in the UK?
Generally it's failure to get tenure (or failure to get on the tenure track) that's considered a failed academic career. Many professors might stop at the associate level and not go on to full professor, but they don't care because they have tenure.

The UK abolished academic tenure in 1988. So nowadays nobody gets tenure in the UK.
In the 21st century, “tenure” is primarily a North American concept (US and Canada), the rest of the English-speaking world doesn’t have it
The main point of tenure in the US is once you’ve got it, you now can’t be fired without reasonable cause. In many other countries, that’s not a special perk for academics, it is a standard aspect of employment law for all non-temporary employees - making the whole idea of “tenure” rather meaningless
