I think the prime way in which this varies is that I don't see a rogue without reckless attack not still having the ability to sneak attack consistently.Well, I'd prefer the ability to sneak attack consistently over two more rogue levels, YMMV.
So it isn't a choice of "sneak attack consistently" or "two more rogue levels" so much as "sneak attack consistently with 2 levels of barbarian stuff" or "sneak attack consistently with 2 more levels of rogue stuff"
