Here's the thing nobody tells you when you're cross-shopping these two spools: this isn't a brand decision, it's an equipment decision. The SUNLU ABS and the Overture PETG cost within a couple dollars of each other per kilo, and both exist to solve the same problem — you need parts that won't sag or snap the way PLA does. What separates them is what your printer looks like. ABS wants an enclosure and a window you can crack open. PETG will print happily on the open-frame machine sitting on your desk right now.
That's the comparison, honestly. Everything else is detail.
The picks
SUNLU ABS
Budget ABS for strong, heat-resistant functional parts.
$18-24 / kg · Amazon return policy applies
SUNLU's ABS runs $18–24 per kilo with a 4.2 rating, which sounds middling until you understand why: ABS punishes people who buy it without the setup for it. Printed in an enclosure with decent ventilation, it's a genuinely strong, heat-tolerant plastic you can sand smooth and vapor-polish with acetone — the only common filament that gives you that finishing option. Printed on an open frame in a bedroom, it warps off the bed, splits along layers, and stinks up the room. Same spool, two completely different experiences.
Overture PETG
Tough, water-resistant PETG with tight tolerance and dependable spools.
$19-25 / kg · Amazon return policy applies
Overture's PETG is $19–25 per kilo at a 4.6 rating, and the higher score reflects how much less it asks of you. It's tougher and more heat-resistant than PLA, shrugs off water once printed (outdoor brackets are its natural habitat), and Overture's tight diameter tolerance and clean spool winding mean fewer of the mid-print surprises cheap PETG is famous for. Its vices are the usual PETG vices: it strings until you tune retraction, the nozzle oozes a bit more, and it drinks humidity out of the air — a wet spool prints like garbage, so budget for a dry box or a sealed bin with desiccant.
How to actually choose
Ask three questions.
Do you have an enclosure? No enclosure, no ABS. Don't talk yourself into brim-and-draft-shield workarounds — some people make it work, most burn a weekend and half a spool learning why the enclosure advice exists.
Does the part live near real heat? A bracket inside a car in summer, anything close to hot electronics — ABS tolerates sustained heat that will slowly soften PETG. This is the one job where PETG can't substitute.
Do you care about finish? Sanded and acetone-smoothed ABS can look injection-molded. PETG is glossy but stringy, and it sands badly. If the part is cosmetic and you plan to post-process it, ABS wins.
If you answered no, no, and no — and most people do — buy the PETG.
Who should skip which
Skip the SUNLU ABS if you're new to printing, you print in a living space, or your machine is open-frame. All three at once? It'll be the roll that makes you quit. Skip the Overture PETG if you genuinely need vapor smoothing or heat resistance, or if you already run an enclosed printer dialed in for ABS — at these prices ABS is the slightly cheaper spool anyway, and it's the more capable material once you've tamed it.
Bottom line
These aren't rivals so much as two different answers to "PLA isn't cutting it." The Overture PETG is the default: forgiving, tough, and happy on the printer you already own. The SUNLU ABS is the specialist: better against heat, better to finish, and worth it only once you have the enclosure and airflow to keep it flat and keep the fumes out of your lungs. Buy for the printer you have, not the printer you're planning to build.
