Brand names sometimes don't really matter, but if it's oak lump, should make for a decent flavor without being too overpowering. I do know that lump from mesquite burns wicked hot in comparison to briquettes (not to mention it adds a powerful amount of flavor in a closed cooker), but fire control can bring a learning curve, and for longer smokes, lump alone may not allow you to get enough run time from one basket full in a vertical smoker using the minion method.
For open grilling with moderate closed-lid times, lump is a nice change, providing a very hot fire for searing, and most any lump will work very well and give a nice flavor, including mesquite.
Lastly, lump leaves behind far less ash compared to briquettes.
