It definitely gives the season a better chance at a deserving winner but I prefer final 2 much more from a strategy standpoint. It makes the vote at the final 5 much more crucial which isn't as important when there's a final 3. There tends to be a solid alliance of 3 that just knocks out the 2 outsiders and cruise to the final 3. With a final 2 it forces the strategy piece to continue until the end. I'd have to go through each final tribal vote but I'd imagine final 2s have had more drama than final 3s.
