what's easier/better 2 5lb or 1 10lb butt

So the cook time basis of minutes per pound.  Does not really include the plateau or stall time that can occur?

That time is just a best guess and there's nothing worse than having a bunch of hungry people bugging you about when it will be done or not having it ready when everything else is. If it goes according to the 1.5 hour per pound general guideline then great it'll be fine resting in the cooler however if it takes longer than your sure gonna be glad you started earlier
