MSI has not been in the lappy business as long as the other manufactures. They have yet to crack the top 5 sellers of lappies.
Lenovo has serious stand behind their product problems. They bought IBM PC division and proceeded to drive the quality of the system into the ground. Their customer service is well below par. They even makes Dell customer service look good. Lenovo Makes it hard to surf thru their site without signing up to find trouble shooting tips. Sometimes it is impossible to find certain things without giving them your email addy. The last and final thing to remember about them is they are a Chinese Government own company. It is up to you if you want to trust them. Lenovo also got caught shipping system with Adware installed on them called Visual Discovery by Superfish. It was a giant security hole that they intentionally installed for corporate greed.

You get what you pay for. Systems with high end parts with low prices are to be viewed with suspicion. They have to cut corners somewhere to get the price down. What cost you less today is going to cost you more tomorrow.
All laptops or desktops have pretty much the same CPU, GPU, ram, hard drive and screen. Most people do not know that the brand of the hard drive can make all the differences in the world. Intel and AMD make the best CPU. AMD and Nividia make the best GPU. What makes a good laptop or desktop is the manufacturing process, the motherboard and the sub components used in them. After that, it is the software included with them. Some manufactures modify Windows and the drivers severely and cripple the system into being locked to them. Some manufactures so load the system up with bloat software that it takes an hour or more just to get it off the hard drive. You will find those who do not know much about PC and laptops claiming brand do not matter. That they all have the same components in them. The brands makes all the difference. It would be like saying the brand of car, or television does not matter.
I would go with HP or ASUS.
ASUS and HP do not modify Windows as bad as the other manufacturers. They have excellent build quality. They might add a lot of bloat but they also makes it easy to get rid of it. Their customer support and technical service is far better then the others and they have excellent online support. I have dealt with many companies when it comes to this kind of support and these two stand out.
HP has a built in diagnostic program in its BIOS/UEFI that can help quickly find problems in the hardware. They also have a built in method for recovering from a bad BIOS/UEFI update. I have chucked many lappies because of problems during the update and the customer didn't want to pay the cost of replace the chip.
The link below has a list of lappies that should fit your needs.
