I dunno, in my case it just made it faster. Shitty knife can be made sharp, just not for long.
For me it's mostly "the better thing makes it quicker". Sure there is some minimum that makes stuff below impossible, but outside of that it's mostly convenience
The price point for a decent blade is pretty low though. Something mass produced by one of the decent brands gets most of the performance that a home cook is going to notice.
I personally think that keeping knives sharp is a sub-skill of cooking but a very unintuitive one at first, until you use someone else's sharp knife and all of a sudden things just click.
