With Droid Gunship (#75042) we get four minifigs that are better for army building than for collecting unique ones (Chewie fit's in a random wookiee army). Standard battle droid and super battle droid are not rare or very exiting but they're nice add to your droid army. More tips for building a droid army
41st Elite Corps Trooper is a nice add but we get two of them in Kashyyyk Troopers battle pack (#75035) so not a very rare one either. So the minifigs are not very awesome, atleast there could be a few more droids or clones. But overall Droid Gunship's been a nice little build.
