Oman is probably the best. Though they are an absolute monarchy, they've managed to stay neutral in the destructive conflicts plaguing the Middle East, most notably the Saudi-Iranian rivalry. That in itself is a great achievement.

Easy to say when you're comfortably sitting with all your free speech and liberty. I'd also add that it's pretty unfair to call us worse than an authoritarian, theocratic absolute monarchy because we don't "stay out" of conflicts when we're literally everyone's favourite boogeyman in the region. We can't stay out.
Not to mention that staying out of conflict isn't really something that I would consider to be inherently virtuous.
I mean its good for the US to stay out of conflict half way across the world but I think all 3 of Israel's wars are justified considering 2/3 are self defense and the 3rd was a surprise attack days before the other countries would have attacked.
