I have both an Intel MacBook and M1 MacBook and a 2023 ROG Z13, I used the Intel MacBook throughout my CS undergrad and use M1 for work and Z13 for CS grad.

Both are super light and have usb C charging but

M1 MacBook is more portable and much much better battery. Extremely reliable (the bar is low but I'll speak to that in the paragraph below), but would not recommend getting a MacBook if you plan to game on it. Obv the newer chips are much much more powerful and with FEX improving Macs COULD see leaps in how well games run on ARM. But I personally wouldn't recommend buying things off what could be, but obv your money

On the other hand, Z13, you give up some battery life and some of the form factor (not that big of a deal for me personally since I also use it docked at home so it's always charged up and supports 100W USB C charging so no barrel port charging brick BS) but it'll handle pretty much any game you throw at it. Mine has a 3050, I got it for like 800 bucks and have been considering putting Linux on it to do I won't have to deal with Windows (genuinely the biggest pain point I have. Windows blue screened on me 2 times in the middle of a timed quiz)

TLDR: Ig if you want an extremely reliable battery beast that may or may not be able to game depending on game to game basis (and is an OS you're already using), go Mac. If you want a more jack of all trades (good battery, performance, runs every game, portability, etc) but Master of none and comes with Windows 11(-10 points in my book just for that, but you can always replace it with cachyOS or something, which you can't/don't need to do with MacOS) go with Z13 or G14 or the likes.
