Not a fan-boi; I run FreeBSD and Linux and don't touch Windows unless I have to. Long story short, I have a Stealth 13.3" with a 1650 MaxQ. I mostly play X-Plane 11 on it, Borderlands 3, and Astroneer. Thermal cooling wise, it works really well. X-Plane 11 is by far the most taxing on the system. Razer's stuff comes without all the stupid bloatware. Yeah, it's Windows, so I RPZ'd off the Windows "telemetry" and VLAN'd off the garbage laptop; if the 31337 h4x0rs want to steal my saved games so let 'em. All in all pretty much 10 of 10 happy with the purchase.
More recently I upgraded to the Razer Core X and a 2070 Super. Performance on the eGPU wasn't fan-freaking-tastic like I hoped due to 4 lanes of PCIe but it at least doubled the framerate.
Like you, perhaps, I'm often suspicious of "gaming laptops" but honestly my 13.3" Stealth has been really good. BL3 runs on "Ultra" settings. Astroneer never had any issues with the highest settings (minus the experimental graphics). The eGPU works pretty well with X-Plane 11 with everything minus reflection detail tured up to High/Maximum.
Hope this helps. Again, not a Razer fan-boi but rarely in my mind does a company produce a product worth the investment so it's easy for me to proclaim my happiness. YMMV and who knows with this one, I don't own it. :)
