I used Corel, Adobe, Movie Maker, Movie maker live and Sony. Sticked with Adobe for a full editor and Live Movie maker for really quick and dirty edits that don't require more than one audio or video track.
Sony Vegas is buggy, corel video studio keeps crashing for no reason and it's not precise.
Premiere has it's few bugs but it doesn't crash. When you notice the editor acting weird after a few hours, a restart fixes it.
If you're not doing super complicated things, try with Windows Live Movie Maker. It's not the movie maker that comes with WinME and up. It's one you download (for free) with Windows Live Mail and Writer.
