usually those inputs are just designed to fit the impedance, they are
not designed to sound good. Such an input does replace an impedance
converter, such as a DI box or a workaround using a stomp box, but never
ever those inputs are able to replace a good guitar tube pre-amp. I
might be wrong, but AFAIK those inputs are only provided by pro-sumer
interfaces and not by professional interfaces, so don't expect
first-class input amplifiers at all. However, the line in and
mic amplifiers are much likely good enough for most tasks,
but the hi-z instrument input is much likely missing the
characteristics of a guitar amp input.

Before we start another dispute:

sound you want." - https://www.gearslutz.com/board/4241684-post5.html

I don't own a good guitar pre-amp myself, but I used a 19" Hughes &
Kettner guitar tube thingy of a friend. They seem not to sell those 19"
guitar tube thingies anymore, but at least they still provide a stomp
box tube thingy with a red box ;),

know if this stomp box is good, too. The 19" guitar tube thingy I used
improved the sound a lot.
