I've not used that printer, but eSUN PLA+ is my goto filament! It's strong, affordable, high quality and produces good prints. I have found though it wants high temp printing. 225C seems to be the sweet spor on my sidewinder X2.
Try printing a temp tower because it's stringy as fuck or downright brittle at the wrong temps.
I'm actually in the EU too. And i want to get a Prusa MKIV next year.
I don't really push speed in my printing though, I currently have actual print times of about 38m on a benchy with my 0.6mm nozzle at 0.4mm layer height for reasonable quality. Can't speed up beyond 90mm/s without significant loss in quality though. Don't think it's filament related however, had the same thing with other filaments, even stuff like wood and steel PLA mixes.
But yeah, my experience has been that at about 20 Euro a kilo on Amazon eSun PLA+ is excellent value for money. But I avoid their resin's like the plague. Worst resin I ever printed with. .
