to start with the new 3d prusa i3 came woth a roll or pla which was not too bad a few clogs occasionally
went to supplied abs and had nothing but problems clogs prints stop heat issuess and after many checks alterations new parts and not getting very much furter

decied to try and made by rigid.ink and i have had 3 succsful prints no clogs no prints stopping no warping lifiting off beds

so just saying now that having a good manufacture of your filiment makes a hell of a difference and should save many headaches

yes there is a difference between suppliers but even from the same supplier you can get a roll with different needs for settings....
So even from rigid.ink you can get a roll of PLA that is bad.
