I love my Overture brand filament. Eryone has some good stuff as well. You'll find most of it is the same, but you will eventually find what works best for you. Some you will notice just prints smoother, with more consistant layers. For me, that brand is the Overture. I haven't tried their PET yet. What I would do is shop around a bit. Read reviews like a detective looking for clues. See a color ya like - do a little digging then buy it. Everybody has "their" brand. Find your own. I've NEVER not used any roll I have ever bought.
This is some cheap azz ZYLTech.

One VERY IMPORTANT bit of advice, and excuse me for yelling at you, but this NEEDS TO BE ADHERED TO -
ALWAYS:
NEVER, EVER, EVER, EVER let go of the loose end of the filament once you disconnect it from the spool. If you do, you will MORE THAN LIKELY end up with that loose coil getting under a previous coil, and at some point during a print, maybe a week later even, when you least expect it, you are going to have your filament get tied in a knot, and you will have to completely unroll every bit of filament from the spool to correct it, after cleaning all the ground up resin out of your extruder. It WILL happen, and it WILL SUCK!
