I haven't read anywhere near all of them but I really like these ones:
Resurrection (Tales 9) - Vader vs Maul
Honor Bound (Tales 22) - Clone Commandos!
Lucky (Tales 23) - Wedge Origin story
A Death Star is Born (Tales 4) - Comedic take on the horribly designed Death Star
Outbid But Never Outgunned (Tales 7) - Fett family dynamics
