Keeping notes on various FDM printing filaments here. Prices are per kilogram spool unless stated otherwise. Printing was done on a Bambu Carbon X1C unless stated otherwise.
The glass transition temperature is ideal for annealling.

Qualitative comparisons
Manufacturers employ additives to change the properties of their filaments, which I don't attempt to address here. Properties may change across different batches of the same filament. These are very rough comparisons based off oral wisdom.
- Impact strength: ASA > ABS > PC > PETG > PLA
- Tensile strength: PA6-CF >> PC >> ASA > ABS ~= PETG > PLA
- UV resistance: ASA > ABS
- "Chemical" resistance: PETG > ABS
- Melting temp: PC > ASA > PETG > ABS >> PLA
- Heat resistance: PC > ASA > ABS > PETG > PLA
- Printing speed:
- Offensiveness (odor, VOCs while printing): ABS > ASA, PC
- Acetone postprocessing: ASA/ABS only
- Ease of sanding: PLA > PETG > ABS/ASA
- Ease of painting: PLA > PETG > ABS/ASA
- Tendency to warp: PC > ABS/ASA > PLA > PETG
- Hygroscopicity: PA > PETG/ABS/ASA > PLA
- Filament density: PETG/PLA > ABS/ASA
- Hotend temp required: PC > ABS/ASA > PETG > PLA
