What one person likes, another hates, I have 4 Rapids, I wouldn't swap any of them for an hw100.

All of mine are more accurate than me,the mk4 triggers are as good as any other I have tried, even my rapid with the gamo is fine (infact its my go to hunting gun) I must admit though some are rubbish.

Personally I like a self indexing mag, far easier to replace a mag than repair a index system that is fitted to the gun.

As for a q/f and gauge, a cheap an easy upgrade (if that's what you want) but I'm not bothered with those either, more things to go wrong.

3 of my guns have regs, they give a few extra shots with no power curve but they don't make the gun more accurate than the unregged gun.

I also like the scope mounts and the cocking bolt.

Reliability, my old mk1 has shot 100s of thousands of pellets, had it for over 20 years, only ever let me down once, a blown o ring that cost 10p and 5 mins to fix. Other than a recent service on the regs of the other 3, none have caused any issues.
