GoXu, has to do with your play style. If you go talon/wing, you can rush in more and take more chances because your survivability is higher (I'm assuming you're using more Thoth (mana regen) and Isis (health regen) items). If you like to stay back and attack only after someone else starts, then bows will always be a superior group choice. Especially the Scarab bows. Longer range and higher base damage.

I played both for awhile and landed on thoth/talon because I found myself playing way too aggressively and dying more often with just the bow and less mana/health regen. You are definetely more team effective though with a bow. But sometimes if you die more often but do more damage, it balances itself out. Sadly you won't really get to 'try them both' effectively until higher levels and after getting lots of cash because that's when you can try things with a balance of thoth and isis gear.

Good comments from the other 2 blokes as well.
