Our Verdict

Dell Alienware AW3821DW

LG 34GP950G-B

The LG 34GP950G-B is slightly better than the Dell Alienware AW3821DW. The LG has a slightly faster refresh rate and a much faster response time, with significantly less overshoot. The Dell, on the other hand, has better ergonomics, it feels better-built, and it has better connectivity, with an additional HDMI port and two extra USB ports.
