As much as I hate to say it, Han Solo was a terrible smuggler. He got caught, he can't sneak (see ROTJ), he can't dual wield, he can't heal, and if he were a better smuggler, he wouldn't have gotten caught in the Death Star's tractor beam....
Let the flaming begin!
By that token, Luke Skywalker was a total noob for never learning Force Charge or Force Sweep when he hit level 2 and 3 respectively. Scandalous.
And Han was a total scoundrel. He was lazy, sneaky and used one blaster. None of the passive aggressive trigger happiness of gunslingers. Plus, Leia called him a scoundrel repeatedly, I recall.
