Which of these laptops should I buy?

Hi

I want to buy a laptop, but I'm not certain which one of these models I should buy.
1. Sony VAIO Fit 15E SVF153290X - Touch
2. Sony VAIO Fit 15E SVF15328CX
3. ASUS N550JK With Leap Motion
4. Lenovo Flex 2 - A

My main uses for the laptop are mixing and composing music (using Cubase 5), doing basic designing in Photoshop, and occasionally playing video-games.

I've read about all the technical details, and I'm more interested in the actual experience of using these laptops

So, I would highly appreciate answers based on personal experience. No matter which of the mentioned laptops you've had experience using, I'd be more than happy to hear about it.

I will choose the best answer personally.

Lenovo. I've had a few of these laptops and some of their other product. Not this SPECIFIC model so you can dismiss this easily but its was damn fast. Youll need much more ram for those sounds though. Try going a LITTLE higher youll see nuggets. But its okay you can easily upgrade for your model type but its the best bang for your buck honestly.
