is Fives ship Umbaran starfighter good?

I use Umbaran because it can target lock and take a beating. His normal attack must be the least damaging attack. But useful against target locked tanks. So overall a very useful ship and worth getting.

Ashoka can be nice in reserve if you need to remove a taunt or counter (from scimitar) fast. Don't use her in your starting lineup, it's terrible on defence.
