I admit to being old-fashioned and that I keep to ways that work for me. Those not interested need not follow my recommendation.
Therefore, I persist in using line-oriented Spice (not schematic capture), especially for .AC mode to calculate frequency response of linear circuits.
Often, I draw my simulation circuit using KiCad, to label the nodes and component references before manually generating the circuit file.
My software is AimSpice, which is available in a free student version.
http://www.aimspice.com/It's post-processor is efficient: I use it to generate .csv files that I then graph with Grapher (from Golden Software), which is rather expensive but I learned to love it at work before retirement, since it produces "literate" graphs with the format under my control.
Spice files for common semiconductors and analog ICs are often available from the manufacturers' websites.
