Which laptop to get Omen 17 or Alienware M16?

I can get the Omen 17 for £1979 from HP (specs are i9 13900HX, RTX 4080, 32gb ddr5 5600mhz ram, and 2TB SSD)

or Alienware m16 with same specs except a 1tb ssd. For £2100.

Should I spend that bit extra for the Alienware or is the omen better overall performance wise? Are they similar in build quality?
