I'm the market for these laptops. Rn they are on sale for the same price although G16 is $400 more regular price. I'm between the G14 4060 vs the G16 4070. I like the 14" for better portability but I'm getting a better series for the same price on the G16. I also am aware that the bigger chassis on the G16 will help with thermals/airflow. Wtm??
I've only had 14" laptops but last year I tried an M16 briefly. It was a lot bigger than I expected, especially the rubber feet on the bottom which nearly doubled the actual laptop thickness and are not listed in the specs. I ended up returning it and went with the G14 instead. But the 2023 G14 4060 was only slightly slower than the 4070 in the M16 (10500 vs 12500 Timespy) and I think you'll have a much larger real world difference with the 2024 G14 4060 vs G16 4070 (8500 vs 12000 Timespy). So I'd try the G16 first and see if it's small enough for you and if not, return it for the G14 and take the performance hit for the much smaller form factor.
I have seen lots of complaints on this reddit that the G16 has loose trackpad click action that makes it noisy and I've asked people if they can try putting some thick card stock behind the trackpad to fix it, but none have replied if that worked or not.
Alright, id figured the 4060 vs 4070 difference isn't anything like a dealbreaker. Im not an intensive gamer and gamings not my primary purpose. G14 4060 should do the job
