They're completely different basses. Different scales. Different sounds.
+1, due to the scale and different pickups. The traditional considerations (here are mine) probably apply best:
Short scales: Are easy to play (unless you have very long fingers I suppose) and handle (are often light); have a unique, punchy tone that rumbles down on the E string and gets very resonant on the G; are less capable of copping traditional Fender bass tones than a long scale.
Long scales (Fender in particular): Easy to play for typical to long fingers; tone's heard all over the place; fewer concerns about thuddy E strings; Modern Player seems to combine traditional sound with enhanced lows (If the hype is accurate).
For me, I need both basses. I tend to spend more time on my short scales, but often grab a Fender clone to gig with. They're different basses.
