Find out gender through blood test or ultrasound?

We have an option to find out gender through a blood test at 10 weeks, or the ultrasound at 16 weeks!

I want to know the gender ASAP, but then again, there’s something so exciting about the thought of finding out through an ultrasound.

Anyway, any suggestions?! Has anyone done both and would recommend one or the other? I know this isn’t that big of a deal, but I’m just so excited! :)
