on the go for asus zephyrus. any other laptop to compare

these are a few months I'm following laptops to change mine in two months.
I need a 15" but none of them is powerful enough for my needs (little gaming with three screens but demanding games) mostly video editing.
so it has to be 17". which is the biggest I could handle in trail and photo backpack.
As I keep computers many years (think everyone does this) as an investment, and to finish paying it :-D :-D :-D
I'm in mood to choose really powerful laptop to keep it useful i would say, 5 years.

my choice right now is :

looks like it has been rewarded this year as best laptop, but... is there any other laptop close to this one maybe little less expensive, or same price and as powerful, but that would be great alternative ?
