GearScore™ Verdict — Which should you buy?

Sports, Wildlife & Dslr Enthusiasts — Canon EOS 90D (2019): The best APS-C DSLR Canon ever made — 32MP, 10fps, weather sealing, and an optical viewfinder experience no mirrorless can replicate.

Casual & Everyday — EOS M3 (2015): The EOS M3 was a meaningful upgrade over the original EOS M — bringing 24MP, a tilting touchscreen, and improved Hybrid CMOS AF III. Video tops out at 1080p/30p and burst shooting is modest, but for stills photographers wanting affordable APS-C quality, the M3 is a competent used-market option.

Wedding, Portrait, Sports, Video — EOS R6 (2020): The camera that made Canon's RF system worth taking seriously.
