Sorry, that should have read "No one can hold a crossbow steadier than a compound"
I should have excluded those who do not have complete use of their limbs.
I agree with your second statement about getting more out but disagree that a crossbow is a step up because that is a pretty sweeping statement. Crossbows are certainly easier to handle from some respects but it is not easier to hold on target unless you use a rest. They are also far more difficult to shoot around trees than a compound especially when in a tree stand.
