I disagree with this. I was wondering whether to get a WRX or STI. I got a WRX and I don't regret it. It is more than enough car if you're just driving on the road
Yes, if money were no object I would rather have an STI. I could have paid cash for a STI, but I would rather have $10k in my pocket to put down on a house.
Also, if you're planning to drive the car off road a lot, plan on putting money into the suspension (which would be another reason not to get the STI). I don't think the suspension on these cars is made to be abused. And you may want to rethink getting a new car, since you will destroy the paint job. Maybe look for a unmodified 2008-2011 WRX?
