It's cheaper for a similar quality. However I've experienced great pain with online.net: if you do not fit in their box, their administrative pain can kill you. No matter how hard you try to beat it. They will slam you with garbage.

Twice (in different context) I have tried to use online.net and fallback to OVH/Kimsufi. Why ? First time unability for them to sell servers, second time unability for them to get paid.
