-If it's sucking up your resources, then it's taking hits off you, that's a good thing. Even if the thing dies, it's only 50 gp to bring it back, and it probably won't die anyway since it has to go to negative bloodied. So unless your foes like to skull fuck your wolf instead of attacking your party, usually healing surges will be enough. And if you don't want to burn surges you can always send it home when it gets wounded.
-Your move actions probably won't get used much as an archer anyway. So really who cares if you donate them to the wolf.
-The damage is pretty low, but that actually only makes it a better flanking buddy, because it's inefficient for the enemy to attack the wolf. In most cases, it's not the optimal strategy, which is good for you because you won't need to heal the wolf and you can get your allies get the +2 from flanking.
-If you ever go down, you can keep taking actions through your beast. While the damage may seem trivial, remember that the beast can benefit from your hunter's quarry damage, so the beast can at least finish off your last target.
The problem with the bag of tricks is that it takes a standard action to create the minion, and also burns up a daily magic item power. And that's way too high a cost to bring a minion to help you fight.All you've done is saddled yourself with a permanent version of the cleric's knight's summons that burns real resources off your character. Or as Absent points out, just toss some cash at a bag of tricks.
The animal companion takes a lot more damage, and you can basically move it around with only your spare move actions.
As for the clerics' powers, you're again, using a daily utility power, so that's taking up a power slot.
The main advantage of the beast companion is that it's cheap. All you pay is a feat for it. Seriously, that's it. And I'm not talking RoW feat or even 3.5 feat. I'm talking about a 4E feat that you don't' even get to choose. Regardless of what you may think about the best companion, I'd really like to hear why you think that Combat mobility feat is a better choice over the extra versatility and soaking power that the beast gives you.
Yeah, the beast isn't 3.5 awesome, but it's still a damn good choice for a 4E character. I'd definitely go beast ranger in 4E.
