Here I am preferring the base plotting. To each their own. I read words like "aes" "geom" "grammer of graphics" and my eyes glaze over. plot(data, main="title" etc.) is easy enough for me.
There's a few arbitrary codes/conventions to learn at the start. My take is not to look too deeply into them - every DSL/framework has them and in ggplot2's case they only take a very short time to get used to before you have the flexibility and incredible power/productivity of ggplot2 at your fingertips!
If the plot is simple, ggplot may seem like overkill if you aren’t familiar with the library. But once you start wanting to customize things substantially or doing non-simplistic plots ggplot becomes much easier to use than base graphics.
