Eye of the World looks at first glance about a story set on a boat. It's kind of mislead for a new reader. While kind of terrible at least the original EotW cover conveys a group of adventurers being lead by a diminuitive woman and a big fighter despite how he is never depicted wearing that armour (but retroactively wears something like that in New Spring).

The Dragon Reborn, great cover, but Rand had lost his (first) Heron marked Blade by then.

Shadow Rising has a great version of Mat, but even if it doesn't fit with the timeline, they should have given him his Bloody Hat.

Towers of Midnight has got to be my favourite though some of the other are pretty good.
