Oh yeah the HF has a bit of heat creep, just swapped my franken-prusa to a noctua 24v hotend fan and it seems better, I've also found it super filament specific. I also dropped the plate temps as PLA was unhappy in the enclosure with the summer heat, had to do a rebuild and found the tube going into the extruder wasn't flush up and some PLA had blobbed into the void.

I like the dragon specifically because it's fixed in places, I've totally had self induced issues with a v6 hotend which prompted me to look into it in the first place, also was component compatible. I like the uhf a lot on my v2.4, I don't push my printers to their limits but I'm pretty happy with what it can put out with a 24mm^3^/s profile with a standard 0.4 mm nozzle, it's really nice with a 0.6 mm as well.

Yeah that was my experience with the v2, I tinker with it because I can't help myself, but it's been a rock solid experience once I got it dialed in (which I would expect to do with any printer). They're also popular and well documented so there's a lot of information out there. Klipper is also amazing, my experience with it and the v2 was what prompted me to klipperise my prusa in the first place.
