I've had * Hero 3 White * Hero 4 Silver * Hero 7 Black * Max (1) * Hero 12 Black and I still have all but the 3 white. The 3 white was the only 'bad' one I think, one where the camera really didn't live up to the hype for me and hence I upgraded quite quickly. As for my favourite? In the context of when they came out the 7 felt the most incredible, it really was a big jump with the stabilisation. But I probably shot most of my coolest footage on either the 4 Silver or the Max, just because of the time in my life I was using them and the novelty of 360 footage at the time.
Oh me too, in Motosports tho. One thing the later GoPro's offer is the 8:7 sensor. And the 12/13 have GPlog in 10 bit which is the flattest available log file from an Action Camera, helping grading..around 13 F-stops, tested. GoPros generally save in HEVC but can be output in ProRes via GoPro player. I think your 7 offers H.264 as well. Prores from GoPro Player could help minimize surplus re-compressions. The 7 does around 78 Mbps in 4K...the 13 can do close to 300 Mbps on a good card, or even All-I (first and only action cam that can do that).
Guy on YouTube (not paid by camera company) put a GoPro Max 2 low light capture thru Davinci Resolve Studio. Noticeable change? A Hero black is a bit more capable here, more resolution too. This is easy to do! I use Resolve Studio but have never done this. I'd just use a vlogging camera or mirrorless instead. Would not use those for action tho.

Please don't buy a cheap camera, if you can find a second hand GoPro for around 100 I'd recommend the Hero 7 Black, its still an awesome camera and you might find one within your budget.
You can go cheaper, you can get a Gopro hero 3+ or 4 for like 30 euro used if you keep an eye on online marketplaces. But I think a slightly more modern version with stabilization would work better for cycling. (Starting from the hero 7 black they have HyperSmooth, if you're lucky you might be able to pick up a 7 black for around 100 euro).
Weird. I have the Hero 7 and wouldn’t really recommend it for anything. It’s battery life it terrible, so you have to bypass the battery, and GoPros setup to use remote mics is even worse. I ended up buying a front and rear built in dash cam with a 2TB drive and never have to think about it
I second this. I use hero 6 black, it’s pretty ok for me. 4k 24fps(I use lower fps to capture the feeling of speed otherwise everything looks really slow), has stabilisation, good quality and easy to use but I would really like the additional stabilisation hero 7 offers.
