I've tried a bunch of the cheap / unlimited players. Any claim that they offer what S3 offers is usually totally and completely false. Either bandwidth is not actually unlimited or its terrible quality, or storage is not reliable or or or.

With S3 I've never had a problem with data loss. Eventual consistency stuff was totally annoying back when that was the way they did things, though that was documented. Dev support is strong if you are paying for it if you have a config issue. WORM support is great in key areas (regulatory, ransomeware protection for backup durability etc).

There are cheap players and there is Cloudflare. Cloudflare is on a very different level.

Wasabi has the most horrendous reliability record of any provider I've ever worked with. Uploads will be broken for days at a time with no status posted, downloads will flake, it's just not a competitive solution for consumer-facing storage.

Wasabi is a clown show brought to you by the Carbonite guys. I wouldn't trust it at all given their track record.

What is bad about their track record?
