MacBook pro 2015 vs Lenovo yoga pro 3 for video editing and music production?

My Samsung laptop recently broke (motherboard got cooked) and I need a new one desperately for school. I have been researching a lot and I'm torn between the macbook pro 13.3 inch with retina display or the Lenovo yoga pro 3. I have always been on windows computers and know them inside out and I also use Sony Vegas to edit gaming videos and vlogs/action videos/music videos. I know that Sony Vegas isn't on macs or has to be run through a boot camp software. Having said this I wouldnt mind learning how to use macs and my media teacher at school recommends the mac. I would have to learn how to use iMovie or final cut pro x though. The MacBook pro I have been looking at has 8gb of ram, a 256gb ssd and a 2.7ghz i5 I think. The Lenovo is the same except an Intel m processor And they are both priced around the 2000AUD mark. I will be needing a long battery lasting the whole school day with the ability to edit photos and videos and also I'm looking to do some music production for my rock band later. So which one should I get keeping in mind it would be my first ever mac and the things I need to do. How fast would Sony Vegas run on either?
