Got a light, mate?
Which is deeper?
That really depends on the group ... gamers would have more fun with Snow Tails, families would much prefer Savannah Tails. In Snow Tails you really have to manage your hand and think 2-3 turns ahead, whereas in Savannah Tails the decisions are more immediate. In addition, the movement mechanism in Savannah Tails requires a lot less thought!

Again, that really depends on the group with whom you'll play most.
If your group enjoys formula de, which would be to their liking?
Probably Snow Tails.
