LTSpice - in the right hands -
can help you understand what's going on on the bench quite a lot faster
than bench work on it's own.

 It can help you understand what *should* be going on but bench work shows
you what is really going on and it is up to you to understand why.

But quite a lot of what you need to understand in bench work is captured by a decent simulation, and a whole lot faster than you can capture it on the bench.

learning by benchwork is slower because it is complicated by having to
deal with reality.

Simulations capture quite a lot of what is going on on the bench.
Sometimes the reality you have to deal with is easier to dig out of a well-set up simulation because you can fiddle with stuff in the simulation that you can't twiddle on the bench.
A great deal of electronic design is getting the right concepts together, and while bench work is usually a safer way of doing that, it can also be quite a lot slower.
The subjectivist audio people get quite sentimental about what their golden ears tell them. Peter Baxandall was an objectivist.
