What video editing software is best for an amateur film maker?

Hello all,

Recently my friends and I have been busy spamming the internet with our frivolity and humor via a youtube channel. Thus far I’ve been using my mothers laptop and imovie editing software to edit our skits. It’s fine and dandy for now, however pretty soon we’re going to be getting into some more heavy duty filming.

So I was wondering what different film editing softwares everyone else uses? (Also I’m using a PC for this now, not a mac.)
