There are only a few reasons to consider another SUV above a Tiguan. Boot space and actual offroad capbility may be valid reasons.
As a whole I don't believe you will find a better allround package though. Wheels Magazine agrees apparently. Read the SUV Mega-test here:

After much reservation my wife finally agreed that the Tiguan is OK for her after not being happy with the boot initially. Having my kids (8,10&12) sit in all the small SUVs (including the Q5) and report on which they found the most comfortable, the Tiguan finally got the nod. In the end my kids' comfort on a trip lasting more than 20mins was the deciding factor.
Other advantages was just a bonus for my wife, whilst I obviously had other criteria
