Both Purse and Bambu make very good filament. Unfortunately I bought some Spectrum PLA and PETG and individually they are good but I had been using a different supplier’s filament for some camera parts that I use PLA as the support which was working just fine. The Spectrum is just not doing it. So back to what worked. Coworker had some Sunlu stuff and it disintegrated while still on the spool!

We've had good results with Verbatim and Overture PLA.
(not on a prusa, but lulzbot taz6)

I'd start out using PLA, to build experience. It's a lot more forgiving starting out. I think Prusa gives you some filament with the printer. Mine did, anyways. I have a MK4, haven't done the upgrade yet to MK4S. The Prusa branded filaments obviously print very well on their printers.

I do have to warn you that even Prusa can ship wet filament. Eventually you may need to buy a filament dryer, especially if you start printing some different materials. Wet filament will make you wonder what went wrong with your life, it snaps, crackles and hisses, and in my case had excess adhesion to the build plate. I ruined a build plate that way. I used to have terrible time printing TPU and some PETG, it was because the filament was damp. Once dried, the same filament printed great.

I've printed with Sainsmart, Overture, and Prusa filaments. All worked fine, especially when dried.

^^^ this very important and filaments like TPU soak up moisture from the air like a sponge. Dry vs not dry filament prints are like night and day.
 
I prefer Bambu pla and petg and elegoo pla, bambu is only from them and takes a while to get. Elegoo comes quickly from Amazon. I have used elegoo pla+, rapid and pro. All ok.
I’ve had mixed luck with sunlu, got a few bad spools after lots of good ones. Running a Bambu P1S.
 
This year I made my first parts with carbon fiber filament. This requires a hardened steel nozzle. The best filament I have printed with so far, doesn't twist, warp and is absolutely RIGID. Obviously this is for structural parts or where strength and dimensional accuracy/rigidity is required. Not an economic choice for arts and crafts type prints.
 
I use Polymaker and Sunlu (Amazon) almost exclusively. Never had a problem with either, but hate the cardboard spools from Polymaker...

I started out with sunlo. Because ready available from Amazon. I have had trouble with first pass sticking, I tried hair spray but no help. I’m gonna try glue stick next.
 
I have had good luck with Overture and eSun. I also have a Prusa MK4S.

Next time I need filament I'm going to try some from Print Solid, Prusa's partner here in the USA.
