Any crossbow works fine
I have a $100 used Barnett, pass throughs pretty much every time
any 150lb crossbow is equivalent in power to a 75lb vertical
So anything 150 is good, 180lbs I imagine would give pass throughs every time.
It's not worth sinking 600 into IMO
The only thing that matters is accuracy. My single wheeled Barnett does me good out to fifty yards, which is plenty. so for 100-200$ you can kill deer within 50 yards every time. We've never lost one using it. One even piled up dead in its tracks 15 yards from my blind. Now that's my hunting style, I get in close and get the job done.
with a fancier newer one I bet you could touch them out to 100 yards, but who would need to? maybe you'd have more energy coming out of it because of varying factors but 150lbs=150lbs.
So to answer your question. Best crossbow? The one that will kill a deer.
So any crossbow you pick will be just fine. But IMO if you're thinking 600 ud be payin for looks.
Unless you get pse ar15 mod, now that's worth every penny roflmao
