One experience I had was to find out the sights are not the same. I prefer the adjustable rear sight with the insert, and I don't think it is found on the base model. Of course if you mount a scope then the rear sight is not an issue. Another thing I found among multiple rifles also involves the rear sight. In some cases, the gun can be hitting on center, but if you look at the rear sight, it looks cockeyed or favoring one side of the barrel. I made the mistake of adjusting one of mine to put it dead nuts on center. Only to see I was way off on paper. I ended up drifting it back to where it doesn't look right, but it was spot on.
One of my Henry rifles cannot miss very small (one inch) outdoor plinking targets shooting Federal 40 grain Champions. Another will score a maximum of 100/100 indoors shooting Eley Sub-Sonic Hollow Points.
