But it is fair that e.g. LTspice has a terrible GUI. I always thought QUCS had the best UI of all the free options:

Unfortunately it's not the most popular project.

a) You want to check that your components won't physically bash into something else you care about
b) You are designing something that operates at RF to mm-wave frequencies and need to worry (a lot) about the spatial location of the high-frequency components and nearby conductors / ground planes
c) You want to get an idea about airflow and heat dissipation on power electronics and/or modules (such as power amplifiers) that come with their own heatsinks (some SIPs do!)
Kicad and other bits of more hobby-orientated software that do a 3D render (such as diptrace) tend to do it for reasons (a) and (c). Software that does (b) properly costs hundreds of thousands of €$£ per year to rent and tends to have a UI that makes you scream with frustration at every possible moment.
or at least software that gives you an error message when it fails instead of a blank white page
