The difference in jump range is more than just raw jump range difference. There are more than twice as many stars within a 32LY jump range as there are in 25LY jump range. TWICE. That not only doubles your options for exploring, it also increases the likelihood that you can travel in a straighter line to any ultimate destination you might have.
This is a big part of the reason why my 30LY range combat-fitted Asp can reach the edge of the blue jump path sphere in ~2 jumps, while my 15LY range Vulture takes 3 to 4 times as many jump to go the same distance ...when it doesn't have to turn around or go sideways to find a scoopable star.
Is all relative....you see it as disavantage, I see it as opportunity...even more when I go for some stretches on economy route....the more systems you hit, the more chances to find ELP, and what have you...ultimately exploring for things in the systems, like planets, is better to visit many systems....explorign to reach a region in a galaxy, is more sensitive to jump range... is a matter of style...
My Asp can jump 30ly as well...but rarely have I used the whole range...after all I am just heading to the core....same reason why I dont see a conda with 4 more ly as all that superior when it comes to exploring....but I know for some it is due to reach...
On the other hand, than number you mention, might be true in some regions, and not in others, its all depending on density...
