I'm a fan of the wider/thicker/low rocker shortboard trend going on. Not ideal in tiny mush or overhead bombs but for the majority of the swells we get on the east coast they go great.
i second this. these types of boards work well in even slightly overhead stuff too. an rnf type of board would be a good choice as well. for me, it's a 6'0"x20 1/4"x2 5/8" dumpster diver type board...full rails, wide nose, & wide tail.
if you want to surf most every day and were limited to 1 board you couldnt go wrong with a 7ft funshape. easily duckdivable,able to catch the big stuff and useful as a log. of course id prefer to ride a hp shortboard daily but thatd be too frustrating
