That would depend on your criteria. For example my MSI laptop blows my mbps out of the water performance wise (I have 2 mbps btw 2014 and 2016- so no mac hating here), but it's about 4 times heavier :) but I don't have to haul it around too often.
If I had to haul a PC laptop around - for mbp - comparable form factor/weight I'd look at high end razer laptops. I'm also not a fan of glossy screens, razer has a matte screen option available (so do MSIs but again they are BIG).
Compared to the 13" rMBP, you get a smaller display and almost two hours less battery life (and people are up in arms about the 13" rMBP being a regression on the battery life front compared to the previous model). It's not a replacement for the rMBP, just a less good, but cheaper, alternative.
Not sure why you decided razer stealth @1.4K is closest to what Mac has to offer when they have a "regular" razer blade in the same price range as the mbp with the only upside to mbp being a better battery life (which is most likely due to a superior but hungrier video setup on the blade).
speaking of battery life - not sure that once you get into 6 hrs vs 8hrs type difference it's all that important.
