currently I am looking for a video editing tool for christmas

I am going to use it not only for AMVs but for my own AVCHD videos from my Lumix G6 as well.
I narrowed down on the following tools:
Sony Movie Studio 13 Suite
Adobe Premiere Elements 13 (in a package with Photoshop Elements 13)
Corel VideoStudio Pro X8.5
Cyberlink PowerDirector 14
I have downloaded the trial version where possible. As Corel doesn't offer a trial version are there any users around who could compare it to the other options?
How do these softwares scale to my skills? Which can theoretically deliver the best work (comparing with pro-level tools like Vegas Pro, Premiere Pro/After Effects)? Basically which is the most powerful one in quality and offers the most for higher skill levels?
Thanks in advance for your help!
Cheers,
Stefan
