You must have a very powerful machine. I don't have many crashes when working on high end custom built machines, but they do happen.
From most stable to least stable for me have been:
1) Lightworks (2010 announced they were moving to Open Sourcing the code, still hasn't really happened) It has been used for decades now to make Oscar winning films. If you understand the analog way of editing video this makes a lot more sense. Its basically free but has a HUGE learning curve
2) DaVinci Resolve (Most people use it only for color correction but they have added editing recently) My preferred and the one I recommend to everyone when asked what to use.
3) Sony now Magix Vegas Pro - My previously recommended and preferred video editor does a great job on keeping the work flow the work flow and not getting in your way (Lightworks actually does this best but man it is hard to get through the learning curve)
4) Adobe Premier - This thing is a BEAST but it is the defacto standard. Moderate learning curve but it is cross compatible and has every tool available. Great eco-system.
105) Final Cut Pro - I cringe when I have to use it. Only reason this thing has such a following is it is so hard to learn another video editor. Premier was the standard and somehow Final Cut Pro took over around 2008. Boy I really never liked it, but I was always in the minority till the Final Cut X came out. I have lost hours of work and I have also lost hours of work because case sensitivity is optional on OS X and MacOS.
