As for Razer, I hear their products are excellent (laptop wise).
As for their peripherals, please guys, there's Roccat just down the road and it's cheaper and better.
With Clevo resellers, you get excellent components for the money, but the chassis is usuallt not the 'sexiest'. I'de go with a clevo reseller purely because you can get a rediculous spec for little money (1TB SSD, i7, 8-16GB RAM in clevo world is like 256GB SSD, i5, 8GB RAM in the 'branded' world)
As for Samsung, I've owned one for 5 years and it's still going strong. Flexy chassis though.
HP...sticky keyboard I've heard from friends and wider.
Lenovo...still not forgotten SilverFish crap. As for hardware though, I've heard their business line up is tough and rugged as fck. Suits the frequent traveller I suppose.
Don't talk to me about Apple...planned obselence, bribing developers to not developer for Linux and only MacOS (even though they are 99% the same fcking thing), rip off, etc. Battery is good and heard the frame is rugged enough though. MacOS is obviously stable as hell, depending on release (lol Sierra tho).
As for the others, can't say.
As a preliminary list, i'de say:
1) Clevo reseller (think SCAN, PCS, XMG, etc.)
2) Razer
3) Lenovo
4) Samsung
