Used my VSI as my "attitude indicator" figuring if it was level,
airplane was level. If it pointed down, then I figured my nose was
pointed down, and vice versa for pitch up.

Why wouldn't you use airspeed or altitude for pitch? It responds faster.

When you are trying to maintain constant altitude (or constant
anything) a differential instrument is better than an absolute
instrument. Although the VSI does have a lag, for small changes it
should not be big factor.
Why is a differential instrument better? If I wanted to know if I was
level I would look at my altimeter. If I stay at 6000' I am level. If my
airspeed is faster then I am going down or slower then I am going up.
Now that I think about it airspeed might be better, since turbulence
could be bouncing me up and down and I could be chasing that.
