I'm currently moving from SYS to Hetzner, the prices are much better and support has been great. If you want to get something cheaper than SYS Dedicated boxes I definitely recommend looking at the server auction (which is basically SYS but different). I managed to grab a 128GB server for very cheap.

If you don't have an account you'll likely need ID verification, it was a while ago but to my recollection they'll simply hold the purchase for you while they verify so you don't loose a good spot. Plus you have to do it only once.

Soyoustart servers are not always (ever?) available and connection is not usually the best and they may cannot solve it because of customer agreement.

Also, Support takes much longer, maybe days, to respond.

If you see them as learning servers they are ok, plus you learn to negotiate with support ;)
