How they differ on the data
SUNLU Silk PLA+ runs 10°C hotter on the nozzle (window midpoints 210°C and 220°C), and the two windows share 20°C of range, so one profile can cover both. Polymaker PolyTerra PLA lists the wider window (40°C against 20°C). SUNLU Silk PLA+ runs 17°C hotter on the bed (window midpoints 38°C and 55°C), and the windows only touch at 50°C, so a shared profile has no margin. Polymaker PolyTerra PLA lists the wider window (25°C against 10°C).
