‘UK bike’ meant in the terms of not the Alps, North Shore Vancouver, the places where natural trails are big. 100mm is plenty for the vast majority of UK riding, but totally agree, it is all about having fun and enjoying what you’re doing. Don’t do it for someone else, you ride for your own enjoyment.
Me, hardtail everytime but as having owned an Anthem, really rate them.
If I were to be limited to one bike, it would be a Scott Spark 20, a Giant Anthem or my current bike Cotic Soda (100mm set-up).
Just get and ride, having lots of fun 😀
