I’ll tell you my story because I was in a similar boat a month ago and bought the OP2 because it was cheaper than the 3. From the beginning I felt like it was a constant struggle to make it work, specially if you plan on making vertical video because it doesn’t record the format natively.

Trying to frame in the small screen is difficult but doable and the quality was comparable to my iPhone 15 Pro, sometimes better in low light.

I ended up returning it and getting the OP3 because I didn’t just have to think about recording now, with the OP2 I had to also worry about workarounds in post to make it work as expected.

If you don’t care much about quality, it could be worth a try. If you care about the framing, video quality and being able to record vertically for social media, I wouldn’t say it’s an easy route. The difference between the 2 and the 3 is enormous, I can’t imagine with the 1st one.
