Given those are the only two brands of laptop I've ever owned, and had troubles with both that I think are unusual... I'd steer clear.
I've never had an issue with my MacBook pro but both Mac and MSI tend to be expensive. MSI tend to make gaming laptops so they would be overkill.
ASUS are fantastic value, HP tend to be decent as are Dell. Get an Intel processor unless the laptop comes with AMD's Ryzen processor (which is unlikely as they are very new).
Without naming your budget it is very difficult to say.
$300-$400 will get you an i3 processor.
$400-$600 will get you an i5 processor.
You are probably better looking for the best value with the most ram. 4gb is at the lower end these days and ideally you should be looking at 6gb to 16gb.
For video and photo editing you'll want lots of space, so a hard drive of 750gb - 1tb is a must.
Absolutely. I’d be wanting to test video editing out ASAP otherwise your not going to get value for all that power just surfing and doing emails.
