Just upgraded from a 2014 MacBook Pro 13 with i5 and 8GB RAM. Don’t get me wrong the new m4 air is nice but I was a little underwhelmed. 
1. Screen on the old MBPro seems sharper at least the text does. Maybe cos it’s running OSX Big Sur.
2. Keyboard and touchpad on the old MBPro are nicer to type on.
3. Apps load and run faster on the new m4 but the difference is marginal. At least for basic email, browsing, MSoffice.
4. Battery life is much better on new m4 air but I’m impressed I can still get several hours on my old MacBook.
4. Nicest part of the m4 Air is the midnight color and the extra storage space
