Same here, Sindatur. Where Garak is concerned, it's all gold. Even when he's not the focus, he steals pretty much every scene he's in.
Although if I had to pick a favorite moment, it would be when he, Bashir, Worf, and Martok were in the Dominion prison, and he crawled back into that cramped crawlspace to work on the transmitter, even after suffering an acute attack of claustrophobia, because he had to finish what he started. It's interesting to note that the two Klingons were the ones to acknowledge how much bravery it took for him to face his fear.
I also love the scene in "Body Parts" where Garak snaps holo-Quark's neck, while the real Quark looks on in horror. Garak just seems like he's having WAY too much fun.
