Strength, Reliability and Price are probably the main ones. Although no matter how powerful the hoster is you want to limit the amount of addons you have on the server and in the workshop collection.

RE: Garry's Mod Hosting 2017 - Key elements you research?
Gmod servers are single core, so you have to look for i3,i5,i7 processors. Intel xeons are something middle and AMDs are the worst. Look for sigle core perfomance if you want to host server with many players and/or heavy addons. Next thing is RAM and disk space. More players/addons - more ram, i dunno how many but for 20-30 players 1GB is fine for linux servers. SSD is prefable due faster loading but HDD is fine too. Third thing is host stability, maintenance features and tech support. One time i used cheap and powerful hosting but it had some problems and sometimes i couldnt even start my server and tech support couldnt help.
RE: Garry's Mod Hosting 2017 - Key elements you research?
I'm collecting some data and just generallyinterested to hear your opinions regarding the hosting market.
What kind of key elements do you research before buying a gmod server with a host?
I see what they provide that's better than other GMod Hostings. Like for example, CridentNetworks and GMCHosting both offer different things that almost all other server hosters does.
