I have a mid 2019 intel i5 13" 128gb that l’ve been using for almost 4.5 years now. I mostly use it for photo and video editing (Raw files and footage from my drone). It still works fine but the battery probably only lasts 1-2 hours which is why I pretty much always use it plugged in. I was thinking of getting the 14" base M3 pro model with the unbinned chip and hoping that the smaller form factor wouldn’t be too small as it does seem more comfortable to carry around.
Honestly M1 is more than enough if all you want to do is office work
