I’d go with the Wild Unknown Animal Spirit deck.
The guidebook is solid. Each animal has clear interpretations that make sense (unlike when I tried to apply RWS meanings to a fox card and confused myself). The artwork looks good without being too over the top, and it’s reasonably priced.
Coming from RWS, I found the animal symbolism easier than expected. Having the meanings spelled out helps, instead of trying to remember if that bird means messages or transformation or that I need to stop buying decks.
