Visual wear on Dopplers is mostly found on the corner of the blade, and even a 0.03 can have a "pixel corner" if you get lucky with the pattern seed. You are mostly paying for the "rank" of the item, which matters a lot more to collectors who want to own one of the top ten cleanest versions of a specific skin in existence. If you just want a cool knife to play with, saving that two hundred dollars is the smarter move because 99% of the people you play with won't even know what a float value is. However, if you ever plan on selling it later, that low float makes it much easier to find a buyer quickly because it stands out in a sea of average listings.
