I think Google Cloud requires less domain-specific-knowledge, which is a big plus. And, as a consequence, you're less likely to end up with an expensive and complicated mess.

But if price or performance or user privacy is a concern, none.

I'm a big believe in dedicated hosting. There's tens of thousands of options. Not affiliated with any, but in the past/present what I have/am using and would recommend: webnx.com, reliablesite.net, hivelocity.com, hetzner.com, ovh.com (and their other brands), leaseweb.com we're currently considering phoenixnap.com for a warm-standby DR site (but no experience with them yet). Also, Softlayer pre-IBM acquisition, but that's just sour grapes.

Depending on your specific needs, then Hetzner seems to be good value:

They have a good reputation for stability too, unlike (say) Scaleway. ;)
