Here's the honest version of this matchup: it's close. Both are mainstream PETG from high-volume brands, both land around twenty dollars a kilo, and both will turn out a solid outdoor bracket or enclosure without drama. The real difference is consistency versus cost. Overture ($19–25/kg, rated 4.6) charges a little more and puts it into tighter diameter tolerance and clean spool winding. SUNLU ($17–22/kg, rated 4.4) undercuts it and accepts some batch-to-batch variation, mostly in color.
That's the whole gap. Neither brand is hiding a killer feature the other lacks, so the decision comes down to how you print, not which spool is "better."
The picks
Overture PETG
Tough, water-resistant PETG with tight tolerance and dependable spools.

Overture is the roll I'd hand to someone printing PETG for the first time. PETG is already fussier than PLA — it strings, it oozes, and it drinks moisture — so you want the filament itself to be one variable you never think about. Tight tolerance keeps extrusion steady, and clean winding means the spool won't tangle and bind halfway through a long print. Layer adhesion is a real strength here, which matters because strong layer bonds are the main reason you're buying PETG instead of PLA at all.
SUNLU PETG
Budget PETG that prints cleaner than its price suggests.

SUNLU is the volume play. If your printer mostly makes brackets, jigs, enclosures, and other parts where function beats finish, the price per kilo is hard to argue with, and the color range is wide. The trade: color consistency varies by batch — if a project's parts have to match, order everything at once — and rolls sometimes need a drying pass out of the box before they'll print clean.
How to actually choose
Buy Overture if the print matters more than the two or three dollars. Multi-day prints, parts that live outside, anything where a mid-print failure costs you more than the price gap — the extra consistency is cheap insurance.
Buy SUNLU if you go through filament in boxes. At volume the savings are real, and functional parts don't care about a slight color shift between batches. Get a filament dryer if you don't own one. That advice applies to either brand — wet PETG prints badly, full stop — but SUNLU is likelier to need it on day one.
Two wrong reasons to pick a side. Don't buy Overture expecting it to skip PETG tuning; you'll still be dialing in retraction and temperature to fight stringing, because that's PETG chemistry, not a brand flaw. And don't buy SUNLU expecting premium color matching across a months-long project — that's exactly the corner they cut to hit the price.
Who should skip both
If everything you print is decorative and lives indoors, stay on PLA. It prints easier, strings less, and looks better with zero tuning; PETG buys you nothing on a desk ornament. On the other end, if you need real heat resistance — parts near a hotend, anything baking inside a car in summer — PETG's headroom over PLA is only a modest step. That's engineering-filament territory, and no PETG brand choice will get you there.
Bottom line
These two are close enough that you can't buy badly, only slightly wrong for your situation. Overture is the safer single roll: higher rated, tighter quality control, the pick when a specific print has to come out right the first time. SUNLU is the better standing order: nearly the same performance for less, provided you'll tolerate the occasional drying session and order matched batches for color-critical work. One roll at a time, go Overture. By the box, go SUNLU.
