Biggest factor is are you willing to hunt with discrimination set low and dig more trash to find the good stuff?
If the answer is yes, then you need a good detector with a good coil that has good target separation with the least amount of masking.
Smaller coils generally work better but, it takes more time to cover an area. Are you a hurried hunter or a slower methodical hunter?
Just pick one of the two, try it for a month, if it feels like something is missing or you don't really click with the machine. You end up like most of us,
either selling it, keeping it and trying another machine. You'll never get a machine that is a perfect fit, you'll get some that come close. Maybe sell it,
in a few years regret selling it and get another like it. To keep the cycle going with the least amount of expense, buy or trade for a used detector from
forum members.
Neither one of the two machines has the edge except for weather protection. One will always do something better than the other. Again be like the rest us,
you just can't own one machine at any given time......................
