If they do sell themselves I'd prefer Paradox as they seem to allow their developers more time and leeway. However they are developing two new fantasy CRPG's right now (Runemaster and Pillars of Eternity) so from a business standpoint I don't see how grabbing Larian would benefit them or diversify their offerings.
Paradox don't develop Pillars of Eternity. They don't even publish it. They only do physical distribution and a bit of marketing and PR. They are a contractor of Obsidian Entertainment, that's all.
