What is better for a founder?

It’s relatively easy to acquire a skill, but changing the personality is not easy at all. So I'm for the second option.

I couldn't see the two options on the website but between Option 1) Managing a highly skilled team with conflicting personality traits Option 2) Managing a very moderately skilled team with better cohesion I would go with 2. I also hope that the team cohesion would motivate them :) I believe hardwork beats talent!
