I think I was getting Jayo PETG from AliExpress. As for PCTG it was from Rosa3D - you can get it directly from them or through Allegro

I’ve printed a lot of Jayo PETG, and aside from having to dry it before use, it was fine (and very cheap).

Im Poland you can get PETG for <30 zł, PCTG for ~80. PETG-CF for a little bit more than the plain one.

I am aware of that, but usually Jayo branded filament is cheaper ;)

I’ve used both. PCTG is much more expensive than PETG (which is one of the filaments you can get very cheap), and does not offer that much over it. Unless you need something with (very slightly) better impact and temperature resistance PETG is way to go. If you need much better impact/temperature resistance ASA/PA is the way to go. I’m using PETG+CF if I need more durability and temperature resistance than the plain one, but avoid CF for stuff I have to touch a lot.

Eryone and Jayo are pretty good (and cheap) too. I didn’t have issues with Tecbears PLA I got from Amazon

Yup, try PETG, it’s pretty versatile and resistant to most things (aside from very high temperatures).
