I found this to be true for a long time, but these days you have something like Fork which is much lore user friendly and FAST! We used to use Sourcetree, which is an abomination in comparison.

I always use(d) the terminal, but Fork is the first time I am considering using a GUI as my main tool.

Granted I haven't had to do anything complicated yet with it, so I don't know if it supports it, but I love it for the basic day-to-day tasks that I do 100's of times a week.
