Personally I would stay away from Razer. I've owned the 2019 Advanced as well as the 2nd iteration of the 2019 Stealth (with the 10th gen Intel and it was horribly slow). The battery life on both was sub par, the usb-c ports are loose, etc. They look nice, but it's all just lipstick. Don't get me wrong, the RTX 2070 that was in mine was great, and I'm sure the 240hz display is nice if you're gaming plugged in. But when on battery that panel drains the battery, and even with just the Intel card running I was lucky to get 2.5 hours max, and that was only running edge chromium, word, excel, etc. Nothing that should be that draining. Sure, you can undervolt more, turn the refresh rate down, lower the brightness, etc but who wants to do that all the time? I bought my machine to use it, not spend an hour or two tweaking settings to get what should be standard battery life in 2019.
Also, their customer service is horrendous. When I needed to replace my Razer Core under warranty because of USB port dropout (something that was fixed on the V2 and Core X) it took over a month to get an RMA, and receive my replacement. Mind you I shipped them mine the the next day after receiving the label. It just sat in their warehouse for nearly 3 weeks.
Like the above poster, I also had the 15" Surface Laptop 3 (AMD though) and the build quality is fantastic (I have since decided to go with the Surface Pro 7 and a desktop (MSI) instead). That 3:2 screen looks massive sitting in front of you hands down. I didn't have any issues with the AMD as others have, but considering you get lesser battery life, an no wifi 6, I'd stick with the Intel 10th gen models. The SL3 esily has the best trackpad I've used in a windows machine, and the keyboard was nice too. I'd say my only real complaint with it was the speakers sounded a bit muffled (to me) as they are firing from underneath the keyboard.
For the same price as the Razer Advanced (at the Microsoft store), you can get BOTH an MSI Trident 3 Desktop (i7 / 16 / 1tb ssd / RTX 2060), a Surface Pro 7 (i5 / 8gb / 256gb) and a surface pro signature keyboard. So unless you really need a crazy amount of power (and terrible battery life) on the go, there are much better options.
Edit: And if you ignore any advice against the Razer do yourself a favor and find a retailer that offers a good extended warranty (Microsoft Complete is utterly amazing), because you are definitely going to need it.
