The Immortal Iron Fist. The whole run, not just the first half. I'm also a fan of some Green Arrow stuff and the aforementioned Hawkeye series, also Daredevil but I've just woken up and can't remember specific arcs or collections other than Fraction's run with Hawkeye. Basically if it has unpowered but skilled heroes or martial arts stuff I'm in.

Also for animated stuff my first love will always be the DCAU in its entirety. Was the first time I was seeing not just high quality, enjoyable storytelling with superheroes but also a fleshed out, interconnected universe for them. Weirdly enough as a kid I was also a big fan of reruns of The Green Hornet, probably because my dad had me idolizing Bruce Lee.
