Bourbon vs Vodka
A bigger gap than most realize. Bourbon contains roughly 30× the congener content of vodka by some lab measurements. The same ethanol dose lands very differently — vodka leaves your liver almost only ethanol to clear; bourbon leaves a parade of byproducts.

Vodka wins decisively. If chemistry-load matters to you, this isn't a close comparison — bourbon's defining characteristics (charred new oak aging) are exactly the things that worsen hangover load.
Which one for which situation
FAQ
Why does bourbon cause worse hangovers than vodka? ▾
Congeners — methanol, acetaldehyde, fusel alcohols, and aromatic compounds extracted from the new charred oak barrel. Vodka has nearly none; bourbon has ~30× more by some measurements.
Is bourbon worse for you than vodka health-wise? ▾
In acute terms, yes — more byproducts to metabolize. In chronic terms, both are alcohol, which has the same long-term health profile regardless of the spirit.
