How they differ on the data
Fiberlogy PCTG runs 10°C hotter on the nozzle (window midpoints 260°C and 250°C), and the two windows share 10°C of range, so one profile can cover both. Fiberlogy PCTG runs 10°C hotter on the bed (window midpoints 90°C and 80°C), and the windows only touch at 90°C, so a shared profile has no margin. Prusament PETG lists the wider window (20°C against 0°C).
