Er....In SuperSpice you can set the connection dot size. A dot can be as
big as the entire schematic if you so wish.

In SuperSpice you can use squiggly line resistors or block resistors.
You can also use notation like 2k2 for 2.2k

Most Spices out there all use the Spice3/Georgia Tech XSpice engine.
Some have done a few improvements. There is of course LTSpice, which is
a significantly faster and has much better convergence then moset

This is of course, very, very debatable. I tried EWB before writing
SuperSpice, and it was evaluations like this that were partly the
motivation for SuperSpice. I personally, found EWB useless. I certainly
note that of all the spices, EWB seems to get quite a hammering in the

Which is not necessarily a problem.

Can you read back in the output file?

I agree, many Spices do not follow normal windows standards, e.g. In
some, you cannot even move components like you can the icons on the
windows desktop. Double-clicking should bring up dialogs etc.
As far as ease of use I would try adding new models in any product and
compare it with SuperSpice drag and drop:-)
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
