Hetzner deploys new features very slowly; that's the main issue with them if you're not prepared to roll your own.

But certainly for SEA they don't make sense, unless you e.g. have any subsets of functionality that are bandwidth intensive but not latency insensitive (e.g. I used to manage a network that was split between UK, Germany and New Zealand, and we used Hetzner for the German footprint and put anything where latency didn't matter, like bulk e-mailing, there, while customer facing stuff was all in their respective country). For that to be worthwhile you need a quite significant volume though.
