Would personally opt for 1 or 5, but that's mainly because I'd find it a challenge to concentrate on the subs for 3 or 4 whilst also doing cardio (AIB looks great tho). Deadwood is an engrossing watch and I've only heard good stuff about Kaos (it's still on my to-be-watched currently).

Subs are no problem for me! I've been reading them for so long that they are second nature.
