There is a slight difference between $12 and $60 vodka.
There is a huge difference between $12 and $60 scotch.
If you do it right, and have a taste for vodka, a $60 bottle is going to absolutely blow away a $12 bottle if served frozen with nothing in the glass. That is the ideal serving method, the next ideal method being with pure ice, not ice made from the tap. That is why vodka drinks are drank quick, served in a small yet tall glass that can only hold maybe two ounces, and is served frozen.
Telling the differences between a $30 bottle of vodka and a $12 bottle? Much more subtle, so much that in blind testing, it'll be difficult if not impossible unless you know vodka inside and out and aren't just a brand fanboy. Most Greygoose fans fall into this category.

So not worth what they charge.
But upwards of $50, differences are there if you care to find them. Actually tasting popov... like trying to find its subtleties, is like torture. I refuse to do it again.
Smirnoff I cannot handle either, tastes like shit imho.
Now for mixing... yeah just go for a cheap vodka, well cheap and smoother. I still won't use Popov, but I like Svedka for mixing, it's pretty close to Absolut but like $10 cheaper the 1L bottle.
But Vodka is something you have to be able to throw many away to really enjoy, because it gets good upwards of $50. I tasted an $80/750ml Vodka that was so different from anything I've ever had, almost would call it vodka. Completely different characteristics.
And most people don't drink vodka straight, so for them I definitely wouldn't say get expensive vodka, you're being a label whore at that point. Nothing about Belvedere makes it better for mixing. You will never know. The other, more flavorful liquors deserve the higher price tags, truth... but it's not a lie that really expensive vodka tastes far different from cheap shit.
