It might depend on which Imperial service is going to use the motto. An interventionist branch - military, intelligence - might prefer something more proactive. I imagine a bunch of guys shouting hoo-ha and assaulting a WMD factory tend to go for a punchier, active, action-y slogan; compared to one which basically describes a motivation.

A more administrative, or, more broadly speaking, a less executive branch might do well with the Remember Earth motto. Here, the described motivation would possibly be more important than the mode of action.

I'm not saying Remember Earth is totally inappropriate, mind you! I'd just prefer something else, depending on the specific service. Imight not have been sufficiently clear on that point.
