Yes, though THC content varies from strain to strain.
From what I gather, many years ago, autos were quite underpowered but I've never run into that. I was reading a write up on 2Fast4Buds and one of their autos is weighing in at 29,8%. Pretty wild. I grew my first autos in 2021 so I don't have any experience with "the bad old days" (well, other than my newbie screwups).
What I've come to see just this year is proof that the key for retaining cannabinoids is to drop temperatures to < 78* after the second week of flower and, loosely speaking, the cooler the better. Based on the research (check out Mitch Westmoreland's two videos on You Tube), I've had my tent temps at least 5° too high but I'm changing my grow environment to fix that.
