Good point - locally just deep diving, also deep wrecks and caves in general. I do go to Mexico several times a year, and would be flying to FL as well, so travel weight is an issue.You don't define what your goals are (deep wrecks, mexican caves, shallow reefs, getting an RB to impress my clientele. etc.) That will make a difference in recommendations.
However If the choice is between a Chop or a JJ (or a Meg) I would go with the JJ/Meg 100% of the time
