Hi,
I have tested many hetzner,vultr,linode,upcloud instances, and the results are very mixed, you can end up on a very good node or not so good one. Hetzner in that matter, seems to offer a very good (not the best) Dis I/O, one of the best CPU performance, but the best price for the specs, so pretty much what your bench showed up.
About the hetzner suspensiones, i have seent those on LET and Reddit, can't comment much on that, i do see many are from China or Russia, and legal issues (that's a guess) for Hetzner to offer them services. i have been using hetzner different services for years, without a problem, and i hope it stays like that.
I have never seen hetzner downtime yet. i also have some instances with linode, not monitored, since are very low-priority things, but never saw an issue either.
at te moment i would say they both are very safe and stable alternatives.
