What's the difference between というか and というより?


From what I know, both というか and というより are used to correct or improve on a
previous statement, but are there any differences between them? For example,
are the following two sentences different?

> 病気だ **というか** 、ちょっと疲れただけなんだ
>
> 病気だ **というより** 、ちょっと疲れただけなんだ




Based on my personal reflection, when people utter **AというかB** they tend not to
prepare what they exactly want to say as _B_ when they start to say it; e.g.
your friend suddenly see something and say "That's _A_!", then you see it too
and find it not as much _A_ at once, so you just start to utter 「 _A_ というか...」
while searching for whatever word it really seems to you. The particle か
represents such kind of hesitation.

On the other hand, I think they tend to use **AというよりB** when they are already
confident of _B_ , or at least have something in their mind when they start to
say this phrase.

You can also put というか in the beginning of sentence to mean "by the way" or
"apart from that" in very casual conversation. というより does not have this usage
but you have それより as a synonym to this except it has less colloquial vibe.
