I think the GPU performance is better for M1 Pro. M3 has better single core performance and a slightly better power efficiency. I don't need single core performance though as I don't do things that need burst performance on a single core. And for battery power, I think any Macbook is way beyond my needs at this point.

Also similar spec'ed Macbook Pro 14 with M3 (non-pro) is above $1900 after tax. Almost 40% more expensive. Not worth it IMHO.
