Too bad you didn't try it before - there was a great free trial before they dropped subscription, but I don't think it's active anymore.
Anyway, the setting is great - that much you know. The missions are mostly standard MMO fare, but they play
a lot faster than
The Old Republic. And then there's Investigation Missions, which are unlike anything anyone's ever done in an RPG and an amazing treat for solo players ('cause they don't require you to do much fighting) if one likes that sort of thing. Combat can be a bit hit-and-miss - there are no predetermined classes, so you need to carefully craft your build to advance. Fortunately, Ability Points are plenty and you can easily farm for extra XP if you mess up.
On the whole - if you can afford it, definitely go for it.

EDIT EDIT: Going slightly off topic, does a one off fee mean that the developers won't be supporting it any longer or is there a micro-transaction system sitting behind it?
As I understand it, patches and some new content (hopefully the Story Missions) will still be free, but most new missions will be sold as DLC packs. You can also pay a monthly Membership fee for some additional benefits, but they're not implementing the kind of "pay-to-win model" that F2P games are infamous for.
