How they differ on the data
NinjaTek NinjaFlex TPU runs 10°C hotter on the nozzle (window midpoints 230°C and 220°C), and the two windows share 5°C of range, so one profile can cover both. SUNLU TPU 95A lists the wider window (20°C against 10°C). SUNLU TPU 95A runs 25°C hotter on the bed (window midpoints 30°C and 55°C), and the windows do not overlap, so each needs its own profile. NinjaTek NinjaFlex TPU lists the wider window (20°C against 10°C).
NinjaTek NinjaFlex TPU ships on a 0.5 kg spool and SUNLU TPU 95A on 1 kg, so compare price per kilogram rather than per spool.
