Verdict: pick PETG for stated print speed up to 600mm/s with toughness the maker compares to ABS, and pick PLA Plus for stated print settings with a maker claim of extra strength over plain PLA. Only ELEGOO states a speed, and only SUNLU states settings, and neither side wins on strength alone.

Petg vs pla plus: print speed
Speed is where the two sides part ways on stated figures. Both ELEGOO listings state a top speed of up to 600mm/s, with the white listing heading its bullet 30 to 600mm/s, and both fit regular printers and high-speed printers. Neither SUNLU listing states a print speed, so no speed verdict is possible on stated figures.
Toughness and strength claims
Both PETG listings describe toughness the maker compares to ABS, with high impact resistance, flexibility and an odorless print, plus good light transmittance with less warping and low shrinkage compared to pla. Both SUNLU listings claim extra strength over plain PLA with better layer adhesion, but they disagree on the multiple: the 1KG spool states 3 times stronger than PLA, while the 4KG bundle states 10 times. Treat both multiples as maker claims.
Print settings
Settings are the mirror image of speed: SUNLU states them, ELEGOO does not. Both SUNLU listings recommend a nozzle range of 210°C to 235°C and a bed range of 55°C to 65°C. Neither ELEGOO listing states a nozzle or bed temperature.
Winding, spools and fit
All four listings promise neat winding. ELEGOO cites full mechanical winding with strict manual inspection, while SUNLU cites its own winding technology and a no-knot claim. Both SUNLU listings state spool dimensions of 8.00 inches in diameter, 2.50 inches in width and a 2.20 inch hub hole, sized for hanging on many printers. Neither ELEGOO listing states spool dimensions, though both fit most 1.75mm printers, naming Neptune 4, K1, Ender 3 V2, Kobra 2, M5 and M5C.
Pack sizes and value
Pack size is the clearest practical difference inside each side. The ELEGOO side comes as bundles: the black listing is a 2-pack bundle of 1kg spools, and the white listing is a 2KG bundle of 1kg spools. The SUNLU side offers a single 1kg spool and a 4KG bundle of four 1kg spools. No listing states a price, so value here means spools per bundle.
Support and warranty
Only one listing states a warranty term. The black ELEGOO bundle lists a 30 days guarantee for any quality problems. The white ELEGOO bundle and both SUNLU listings state no warranty term, so warranty is Not stated for those three.
