Asus doesn't actually make a laptop ... they are made in the same factory by the same OEM's as Toshiba, Apple, Dell and Acer ... so quality can be expected to be no better than the others.
As to the original question .... None of the above. Be aware that:
1. We don't as yet have a desktop GFX card that can power 4k at 60 fps in half today's big games. I'd strongly recommend 3k
2. With a mobile GFX card, the performance will be even slower.
3. The Pixel density on a 17" screen at 4k is 271.48, which is well beyond the human eye's ability to distinguish, the only real benefit from having 4k on such a small screen is being able to tell ya fiends "I have 4k". The 3K AUO screens are far higher quality
4. Alienware laptops, back when they were a recognized make of quality products, had all their laptops built by Clevo; now thy are made by Dell's OEMs..
5. Asus laptops are made by Pegatron, most widely known as the parent company of AsRock, and Foxcon.
Alienware went to Clevo to make the stuff sold under the original Alienware Pre-Dell laptop for a reason.

CLEVO is a large Taiwanese computer company specializing in laptops. While the Clevo brand name is perhaps not widely known, their products are re-branded and sold by known boutique brand OEMs (Original Equipment Manufacturers)… notably Sager, VoodooPC, Falcon Northwest, Eurocom, etc. They are also considered (by whoever knows about notebooks) to design and manufacturer the best of the best notebooks in terms of superior build quality and innovative designs.
6. Many of the brand names that peeps argue about "which is better" are often made on the same productions lines, with the same labor and most of the same parts:
Quanta sells to (among others) HP, Lenovo, Apple, Acer, Toshiba, Dell, Sony, Fujitsu and NEC
Compal sells to (among others) Acer, Dell, Toshiba, Lenovo and HP/Compaq
Wistron (former manufacturing & design division of Acer) sells to Dell, Acer, Lenovo and HP
Inventec sells to Toshiba, HP, Dell and Lenovo
Pegatron sells to Asus, Toshiba, Apple, Dell and Acer
Foxconn sells to Asus, Dell, HP and Apple
Flextronics (former Arima Computer Corporation notebook division) sells to HP
7. Like a desktop, we recommend that if you want a good gaming laptop, like a desktop it should be built using individual components you choose
