I can already see why some reviews including notebookcheck.net got bad battery results - when I got it initially, the package power draw was very high - notebookcheck had it at 17W on idle on average which is quite ridiculous. I currently have it on less than 2W idle after some minor tweaks to software/services start up (thanks Windows...), these tweaks did not limit performance. On idle using just the "Better battery" setting, 40% brightness and keeping the refresh rate at 144hz, Window's is displaying ~11.5 hours of battery life. So for light productivity, I think you can get at least 6-8 hours without trouble, but you could extend the battery further by using "Battery saver" and switching refresh rate to 60hz.
Next step was to lower temps, this isn't a Razer issue but the i7-8750H issue, I wouldn't be surprsied if many MBP 15 users report that it gets hot and loud quite easily. I undervolted by -125v CPU/Core and -50v Intel GPU. Now the laptop ide's in the 30's (degree's C).
Initial impressions is that this laptop in looks/feel is ahead of the MBP 15 which I didn't think a laptop could do. One thing I don't know if many people noticed (you'll notice it on review video's) is that the hinge on the MBP 15 is a bit too loose for my liking, just general typing has the display lid wobble quite a lot. Both machines are solid but the Razer has less flex if you were to apply pressure. The bottom of the MBP 15 is definitely more sleeker though, where as the Razer has all that intake fan vents and feet to raise it. Razer is however upgradable, with the RAM, SSD, Wifi card and battery user servicable.
As others have mentioned, the lack of backlighting the function keys are a bit annoying, especially as the back lighting is definitely the best looking - and you may have to get used to the weird arrow placement (I don't use right shift, but I am continually pressing right FN instead of the right arrow, as I need to do CTRL+right to use as "End"). The Touchpad is MacBook quality and the only issues I faced are some palm rejection on it, though I also experienced that on the MBP's. It is more that Safari is so much better than Edge/Chrome with gestures, rather than the MBP having a better touchpad. The keyboard feels nicer to type than the MBP 15 I guess, but the main advantage is that they won't die like butterfly key's.
The screens are, different. One is a glossy high res P3 500nit screen, while the other is a 1080p 144hz low response matte 300 nit screen. I prefer matte and in some ways, this negates the fact the screen does not get as bright. As for high res vs 144hz, I didn't realise how nice 144hz can look just for normal UI for productivity, even if you're not gaming. On balance, the screen is probably better on the MBP 15 overall, but the Razer one is definitely of high quality. Razer does also do a 4K screen which could probably better compare to those who do graphical/content design.
Both have their pro's and con's. The biggest advantage of macOS is that it just works straight out of the box. Window's, you need to do a bit of work on it at the start to get it "optimised" but it might be worth it in the end, depending on your workflow etc.
I'll play around with it for another week and see if I want to invest in a MBP 15 instead.
