I have owned both. The only difference really is the cupholders, larger cargo box in the back, and slightly updated headlights/grill/bumper. Other than that, it's the exact same truck. Same motor, same trans, same MPG, everything that matters is the same.
The cupholders are 100% worth having, but you can do that yourself for $30 by digging through the junkyard and doing the cupholder swap. Not worth $1200
I would get whichever one has the best maintenance records and cleanest body/undercarriage.
