I recently borrow my Macbook 12" 2017 (8GB/Intel M3) to my aunt and asked for a Macbook at my job (I like to use my own laptop to work but i can use a laptop of the work), a Macbook Pro 2017 base model and wow, the difference in performance is really noticeable.
My Macbook with Big Sur just didn't run fine but i see now the performance of a more capable Macbook in Big Sur and yes, i can tell that these little Macbook 12" are not the best in power..
..but man, maaaaan how i miss that little, beautiful Macbook 12". Yes, is underpowered but is so little, so silence, so portable, so beautiful. With High Sierre it move really really nice (i think a good middle could be Catalina).
I recommend one if you won't need a powerful machine to do powerful things. I use mine with Quickbook, Chrome and some excels so all good and if you will need it to wath Netflix, youtube, some office, just navigate in the web i highly recommend one. Especially if you will move outside your house with this little machine.
