It depends on what you mean by "best".
You can display more digits of precision, which might make you think you're more accurate, but in fact the positioning error is bigger than any difference in the displays.
I seemed to find caches easier with my first GPSR which only displayed two decimal places for minutes of lat/lon (DEG/MIN.MM) which translates to approximately 50 feet, which is a decent error radius. I knew I was within 50 feet, and searched appropriately.
With my newer GPS which displays more precision (DEG/MIN.MMM) I tend to search for the "zero" point but later find out that I'm up to 25-30 feet off from the cache location, especially when there is tree cover.
It's your call whether you want to display more digits of precision than you really have accuracy.
