Jump range is something that experienced explorers tend to want. As a first timer, it doesn't natter, as you're not likely to go far enough out to worry about it on your first big trip (unless you're like me, and decide to keep changing your goal posts as you go).
Jump range comes into it when you are trying to reach far off systems on the rim of the galaxy, trying to navigate through sparsely populated space (as in populated by stars), or you want to get from where you are to where you actually want to be very quickly.
Having said that, I do know of some experienced explorers that choose not to go for extreme jump range, because it's not their idea of fun, and they like using an unusual ship for exploration.
As an example of, me, personally, I'll be on the Dead Ends circumnavigation expedition. From memory, the pace is about 1000LY a day (perhaps less). That's less than 20 minutes for me in Buckyball (high speed mode named after the Buckyball Racing club) mode. That pace is a little slow for me, so I am likely to do quick sprints towards the core (that 10000k LY form the core region mentioned above) to pick off some cool systems and gets some pretty pics. Of course, this is likely to change when 2.4.1 (or whatever) drops, with the promised "de-beige" update. But until then...
