2 years ago I went from a 2011 MBP to a used i7 2015 15" MBP and it was a great machine. I liked the ports and it was really handy to stash a 400GB microSD in the slot for more space. I upgraded the stock SSD to an NVMe and it really made a difference. I went to the i9 16" MBP a year ago and yeah it's new and shiny and faster but not a world-changer. Managing to skip the butterfly keyboard was the big win. The better speakers are surprisingly the best feature upgrade from the 2015 to 2019. Except for the lure of the M1 Macs, a used i7 15" 2015 MacBook Pro is probably the best bang for the buck in the Apple world.
