Can't go wrong really. If you really want Earl of Sandwich, don't be put off by large line at lunch. Moves pretty quick, no more than about 10 min in line.
I was going to say Earl for lighter meal, Wolfgang Express for heartier meal, but I realize I'm probably basing this on what I could get with QSDP, and I don't know if you mean you have dining plan or not. If so, this holds true, and the "cost" is the same. Otherwise, Earl is great and is not too expensive. (Sandwich $5.99, doesn't come with any sides, but still beats the heck out of any other counter service in all of WDW.) WP Express is great but easy to ring up a larger tab there if paying out of pocket.
Despite the more elaborate stuff at WP, they can be equally as fast from entry to getting food.
