The more I google, the more I see there is a group of people that truly love both laptops. There seems to be a healthy mix of folks, content creators, other pros using the Razer, which surprises me a little, but then I'm not a hardcore gamer myself and I'm contemplating that laptop as well.
The Razer has a lot going for it, and my research seems to show a common theme, great performance, stellar GPU, nice screen, nice speakers and very good thermals.
The X1E, the first thing I see is people saying how great the keyboard is. Decent speakers though they are downward facing, performance is also decent (many benchmarks put it slightly slower then the XPS) and I see a fairly consistent theme of it running somewhat hot out of the box (but cooler then the Dell XPS). Fan noise is an issue that is mentioned. Some say its not too bad, others say its a bit too loud (but nearly everything I read about it is that its not obnoxious)
Comparing the two, the X1E comes out on top feature wise, thanks to the 30% coupon code which ends January 24th. The Razer comes out on top performance, thermally and design wise. I'll not discount that I'm spending a lot of money so I want to like what I'm carrying. The Razer is slightly smaller then the Lenovo but heavier. 4.56lbs vs. X1E at 4.06
Decision day is looming thanks to the 24th but the RTX version of the Razer is not available until January 29th, and that probably means the embargo will only be lifted beyond Lenovo's coupon code expiration.
Edit:
Seems that Lenovo updated the THINKJANUARY coupon code, its no longer 30%. its now 25%, still some nice savings. I configured a machine yesterday and the price was lower then what I see today. I opted for the more higher end yesterday but tbh, I don't need 32GB of ram, though a 1TB drive was nice. The next lower model is similar except its 512GB and 16GB of ram. That price point is 2,000.
