Thanks for the replies!
As from what I concluded,
Both uses the INTEL hd 520 so no difference.
XPS 13 - better battery life, nicer display(infinity display)however if you get the i5 model, they only provide the matte display which doesn't look as good compared to the i7 one, gorilla glass. which looks really awesome btw. Other then that, maybe can consider in the service dell provides, perhaps the dell's more expensive because of the service it provides?
Blade stealth - lower battery life, specs are much better, QHD display, i7, awesome RGB keyboard, nice exterior design compared to xps(this is subjective)
I have decided to get the blade stealth. Battery life isn't really an issue to me, perhaps 3-4 hours of normal work should be more then enough time for me to find an outlet. Haha!
Gonna get 128GB QHD blade stealth, I have an extra 256GB SSD which I'll use as an external ssd if I need more space.
Let's hope my blade stealth has no issue, gonna buy through the website in the next few days, hopefully no issue, if anyone wanna stop me from buying please do! I wanna know the pros and cons!
If anyone has more questions regarding blade stealth or xps13 can ask me, I'll try to help!
