Hi Kelly,
I'm not sure "more accurate" is the correct term to use when referring to the 5900/6000/XL Pro meter. My experience seems to be that it "locks on" harder than the digital units I've used, with perhaps the exception of the SunRay DTI-II meter on a Sovereign XS. In other words, the Whites analog meter doesn't seem to jump around as much on good targets as the digital units I've used. I really like the way this meter "works".
I have other detectors with meters as well. I really like the CZ analog meters too. I'm not as fond of the MXT meter, although I am fond of the machine for certain sites, and types of hunting I do.
Overall, my favorite all-around machine still seems to be the XL Pro. It's been that way since using my first 6000 series machine back in the '80's.
