Review on 🖨️ S SMARTOMNI Compatible 270 271 XL Ink Cartridge Replacement for Canon PGI-270XL CLI-271XL, Works with PIXMA TS8020 TS9020 MG7720 - 1 Large Black, 1 Small Black, 1 Cyan, 1 Magenta, 1 Yellow, 1 Gray - 6-Pack by Mike Weaver

It's hard to tell the real difference between Canon ink and this one as I can't compare the two side by side as I bought this ink set after running out of Canon ink. But I'd say that's enough for day-to-day printing of school supplies, especially since a lot of things are now also available on the internet. I'm glad I found a cheap alternative to Canon. I've never used a non-original, but it seems to work.
