Pros
Pro Very flexible in what you can do
You can play as a sentient starship or even as a whole organisation. All rules included.
Pro Uses FATE
This could be a pro or con. A well known foundation as rules. Also you don't need to buy the FATE rules, as all you need is included in the rulebook.
Pro This is a simple but very flexible system, with enough credible, modern sci-fi setting to play most kinds of games with
The system is story-focused and the the setting is human focused but transhuman, so its broad. And massive. But you can also ignore it, easily.
Cons
Con Lore is still a bit scarce
Mindjammer Press is constantly publishing new material, but as of the time of writing this, the source material out now is still quite limited. Especially compared to the more established systems.
