They are much pricier compared to other EU based suppliers: comparing basic PLA, from prusa it is 27.5€/kg with the 2kg spool, Dasfilament and Fiberlogy give you about 16€/kg with their big spools.

I like Prusament, I have bought many spools and just yesterday I received my Prusament ASA “signal white”. For PLA, Galaxy black is one of my favorites and I buy it regularly. For the rest, I don’t see why pay so much more when the cheaper option are also good quality and give me perfectly good results and no trouble.

I am currently printing my MMU3 upgrade with Dasfilament PETG and it works great, came perfectly dry out of the bag, no strings, prints perfectly. 21€/kg vs 33€/kg Prusament.
