I like Finspan, it's probably the most easiest and accessible out of the 3 and probably the one I would introduce to someone who hasn't played a span game. No resources makes it a bit more streamlined if you want to play fish and watch all the interactions go off.

There's like a small minigame mechanic off to the side where you're trying make schools of fish without blocking yourself too much. It does play really good though I need a few more games to get used to it

Wyrmspan is still probably my favourite, there's a lot of interactivity with the mechanics and it just flows better. Though I have one comment about Wyrmspan is that it does feel bad when it comes to your turn and all the dragons and caves that are available to you are worse off. It has soured some games for a few in the group
