I actually prefer the adventurer ending for Spawn Astarion, if only because it's hard to imagine him managing any sort of population and because the epilogue handled that ending in a very inconsistent way that left a bad taste in my mouth. It's true that him leading them makes for a nice arc in where he started (ruling over other people's lives for his own self-interests) to where he ends up (ruling over other people because he cares what happens to them) but I just can't see him as a leader or being happy being a leader, and the adventurer ending also has parallels as well.
