Can confirm. I use Vanilla Ubuntu.

Just pick something. They are all free (nearly all of them), so you can always install something else pretty easily. Spend some time to get your feet wet and get the lay of the land. After a week or two, you'll probably have a really good direction on what you actually want. You can also run them as live oses, so download a few with different Desktop Environments you think are interesting and test them out. Then install one.
But how well is it working?
Yeah, that's a good question. I don't remember reading any documentation from Statcounter speaking about how well that bot detection and removal algorithms work. The last company I worked for did data collection, as we recorded all kinds of metrics from users. We had a team that focused on bot detection. Mostly it involved discovering the bot net and then removing all of their metrics that were accounted for in the system. Then updating the bloom filters so that any further metrics from the known bots would be ignored. Companies were paying millions of dollars for our contracts and every click was getting itemized and charged for. So, trust me, it was very important for my old company to discover and eliminate bots aggressively.
Statcounters sells their statistics and not the data from what I understand. So it does beg the question, how aggressive are they?!
One in every 20 computers
No, it could be 1 in 20 computers. It could be more than 1 in 20 computers. It could be less than 1 in 20 computers. 5% of the page views, of sites that Statcounter tracks, are reported as Linux machines. There is no way to know what percentage of machines are Linux from the Statcounter reporting as it is.
If they like how SteamOS worked, then go with Bazzite. I've used Linux for nearly 3 decades now. At the end of the day, we could nickle and dime the differences and the pros and cons. I don't think it's worth it. Bazzite will be familiar enough, and you can add Bottles to handle other game launchers. That will give you the most kitchen appliance like device.
rclone is pretty reliable. That's how I back up my nextcloud to two different object storage sites. I have Nextcloud dockerized on a VPS in the cloud (among other dockerized services for selfhosting). Been syncing nonstop for 3 years now. I also used rclone to sync all my files from OneDrive directly to my VPS block storage. Rclone is a very underrated utility.
Looks like you are kind of limited because of the resolution. I mean, if you are downloading pictures of big black titties, on such low resolution, you can really only see the left titty or the right titty. You need more pixels if you want to see them both, at the same time. Highly recommend you upgrade to 4k resolution.
