No USA crash test score for HR-V to compare yet. Ligher weight...who cares on that one? Fuel efficient...Crosstrek is rated better on highway. On my test drive on the same route I got 32mpg Crosstrek and 28.5 HR-V.
You are forgetting one major thing....how each drives. This is why HRV4ME likes the Crosstrek so much, as do I and others here who have also test driven both vehicles. I was all set to buy the HR-V and was just waiting for one to come in, then I test drove the Crosstrek and the HR-V on back to back drives on the same route. The Crosstrek drove much better, IMHO. Much smoother on a road that has a lot of shallow potholes, and better handling on curves.
Comments like "Lighter weight...who cares on that one?" show a lack of mutual respect for others opinions.
These are both very good cars. There are many subjective or non subjective qualities to be compared, and each person has their individual priorities.
If you have driver both, and find for your priorities the XV is a better fit, please go and buy one. No need to insult others.
The weight of a car may be more important to some then others.
If effects things like weight per horsepower, which many people do care about, and also the HR-V is the winner of.
As someone that has had a Honda Civic as my only family car for the last 20 years, weight is important to me.
Weight equates to the amount of force applied throughout the frame of the car, engine, transmission, drive-train, suspension, bearings, brakes.
This happens in every acceleration, deceleration, around every corner, over every hill.
When it comes to long term reliability, operating costs,a lighter car has advantages.
