Is Titos really that much better than bottom shelf vodka

Is Tito’s really that much better than bottom-shelf vodka? I’m somewhat new to drinking, so I’m not really seeing how Tito’s is worth around $40 for a handle when bottom-shelf vodka is like $13. Is there actually a big difference, or is it mostly that cheaper vodka gives you a worse hangover? Again, I know this might be a basic question, but I’m still new to this.
