Quote #10
He was valiant in battle, though his left hand was scarred and of little use, and a cunning strategist; he led his people to victory against the Northern Goblins when they closed the passes to travelers; he forged a lasting peace with the Eagles of the High Crags, a peace that remains in place until this day. (Epilogue.14)
Tristran remains brave and courageous throughout his rule of Stormhold, according to this. Maybe he's not the top warrior in Faerie, due to that little "let's stick our hand in the fire" incident back at the inn, but he seems to make up for it with bravery and skill. And that, in turn, sure seems to make him a good ruler.
