Just my opinion but beef is very much different than pork in terms of texture and taste. However, that doesn't make it bad. Just different. My favorite pulled beef recipe is to follow Fire It Up's italian beef recipe. That comes out just incredible in terms of flavor when shooting for pulled beef.
As for smoke, I don't perceive to be too much different than pork. I prefer a mix of hickory and oak for beef.
For an idea, follow Fire It Up's italian beef recipe to the letter. If that doesn't sound good to you, oftentimes I will use a combination of kosher salt, pepper, garlic, onion and ancho chile powder. Let it smoke until it hits 205*. Put it in a cooler shrouded in towels to rest for an hour or two and then pull it. It works great for quick and easy burritos and a ton of other things. For my burritos I use pulled beef using the rub I mentioned, some pico, a little sour cream, a little cheddar, and some black beans all rolled up in a tortilla. It is my wife and I's favorite pulled beef meal.
