Which is better for functional parts?

The Polymaker PolyLite PLA Pro. Its toughened PLA Pro formula resists impact better than standard metallic PLA, which is the Bambu's base material.

Which looks better on display models?

The Bambu Lab Metallic PLA. Its metal-look finish hides layer lines and gives decorative prints a sheen that plain PLA Pro does not.

Can I print the Bambu filament fast?

Yes. It is rated for speeds under 300 mm/s, well above the Polymaker's 200 mm/s ceiling, so it suits fast printers like Bambu's own.

Is the Polymaker worth it for a beginner?

Yes. Polymaker lists it for beginners, and its 50 to 200 mm/s range works on stock settings for most FDM printers.

Which lasts longer in use?

The Polymaker. PLA Pro is tougher and more impact resistant, so parts survive drops and stress better than standard metallic PLA.

Do both fit the same printer?

Yes. Both are 1.75 mm filament on 1 kg spools, so they fit any FDM printer set up for 1.75 mm material.
