The numbers that matter
Empty, the Stanley IceFlow 2.0 reads 24.6 oz and the Owala FreeSip 14.1 oz. That 10.5 oz gap rides along every time the bottle leaves the house.
At the base it is 3.76 in against 3.24 in, a difference of 0.52 in that decides the car cup holder question.
Neither is a screw cap. The Stanley listing says leak resistant, and the Owala adds a lock that you flip down over the button. The Stanley holds 6 oz more and has a side handle; the Owala is narrower and lighter.
Both makers put a cup holder line on their listings, and both deserve a second look: Stanley's base is 3.76 in, and Owala's own listing warns its 3.24 in base is wider than standard. For a bag, the Owala is the one, because its lid locks. Many people own both. The Stanley stays in the car with its handle hooked over the console, and the Owala goes into the work bag in the morning, which costs about $65 for the pair and ends the argument.
Both, in short

FAQ
Which is better, the Stanley IceFlow 2.0 or the Owala FreeSip?
Car commuters, the Stanley. Everyone who carries a bag, the Owala.
Can the Owala FreeSip replace the Stanley IceFlow 2.0?
Only if it stays upright. Stanley's flip straw is leak resistant, while the Owala's loop locks the lid.
