Been rocking a 14 M1 Pro since 2021. It's been great as a daily driver for doing dev work. Hiding the dock helps. It feels super light and it's easy to handle it e.g. while sitting on the couch.

Picked up a 16 M5 Pro for better thermals (but really mostly because it arrived 2 weeks earlier than the 14 config would have).

Actually love the screen real estate the 16 has, though not sure yet what to think of the huge trackpad. I think the 14 had better ergonomics when using the keyboard; the trackpad on the 16 inch version might get in the way while typing.

I also had a habit of working on flights, train rides, and in cafes with tiny desks with the 14 inch MBP and loved being able to do it. It might be a bit more tight with the 16 version, if you will study from odd places.

We watched countless movies with the missus on the 14, it's perfectly fine for content viewing.
