Good electronics simulator for beginner?

It did DC Steady State, AC and Transient Analysis.  It also did sensitivity analysis for iterating over changes in component values.  The only problem was it just printed pages and pages of output.  I changed the code to punch the data to cards and wrote a little ditty to read the cards and produce a plot on the drum plotter.  My Bode' plots were a thing of art.

I have the source code and the 360 version of the documentation but I don't recall whether I ever got it loaded on my FPGA incantation of the 1130.

I remember ECAP but never used it.  You are 'slightly' older than I!!

Another vote here for LTSpice.

I've been using Qucs (Quite Universal Circuit Simulator) for many years.  Works well for me.

LTSpice is a lot more clunky and less friendly than the more modern real-time simulators. Having things move and change in real-time is a boon. I'm not saying LTSpice isn't a very useful tool, but they seem to do somewhat different things. Real-time is good for seeing what circuits do as you mess with them and getting to grips with certain basics, whereas LTSpice is ultimately more versatile and a real engineering tool. They can supplement each other perfectly well.

Please explain the point here and examples of what you seem to believe is a better approach.
