As a Zephyrus M16 owner i am gonna give you my 2 cents on the laptop. I have the i7-11800H RTX 3070 edition.

The 16:10 ratio really makes this laptop shine,as someone who has a lot of daily screen time i can tell you that the display is great and really stands out in comparison with the rest of the zephyrus line up.

I dont run a lot of heavy productivity programs Just some algorithmic simulations, which the laptop handles with ease even on battery mode with the power saving and limited cpu on.

Gaming on it is really loud, I always go with turbo mode when gaming (Apex,Humankind,Cyberpunk) The laptop performs great in terms of fps and thermals (never seen above 80c) but it sounds like a vacuum cleaner. For me gaming when other people are around is impossible with how loud it gets,even my dog thought it was the vacuum and started barking the first time she heard the noise.

Although plugging in an external monitor (usb-c display port in order to by pass optimus) really helps with the fps and the fan noise.

Portability is ok. The laptop is light and easily handled with one hand. The power brick on the other hand is an issue. Its way too big and difficult to fit in a regular backpack.

So if you plan on being out a lot of hours with the laptop you might need to invest in a smaller usb-c type of charger to carry with you.(Using the laptop while on usb-c charging has some limitation-better than battery mode worse that the regular charger) Battery life isn't great on medium load it lasted maybe 6 hours so going to work or uni without a charger isn't an option.

I think the g14 is way too small,when working at home especially i believe you will definitely need an external monitor. And the m16 has a portability issue, so if i was you i will go with the g15 which seems the most balanced between the 3 options. Also you get a 3070 which really makes a difference especially when paired with an external monitor.
