3 | 3 | In general x2go is easier to use and sufficient for most scenarios. Xpra has better performance and uses less resources. Both clients connect through ssh and are generally faster than ssh -Y. Support for these is beta, x2go is more familiar to the support staff. Most linux systems do not have these tools installed, so you may need to request them. |

5 | 5 | We recommend using x2go. x2go is more familiar to the support staff and it is easier to use. |
