I had a bad experience with Toshiba. However, I'm not sure I can judge since my laptop was refurbished and has AMD processor. I suffered from overheating and battery draining issue since my first few days.
As Georges said, Sony has a better built quality.
The Toshiba has better technical specs, however, if you can spend more money, go for this:

Don't worry about having a slightly smaller screen, you wont notice the difference between 14" and 15.6", but you might notice the difference in weight.
This Vaio has 1X4GB Slot, so you wont have to worry about replacing the existing slot with another one, you will only have to buy additional 4GB to boost it to 8GB. Its HDD is 7200rpm.
Its better to invest in a machine that has a USB 3.0 Port, but don't worry about not having a Blu-Ray Player.
The Backlit keyboard will be helpful when using it in a dim conditions.
GoodLuck! :)
