Upgrading my MacBook Pro (13-inch, 2020, Intel Core i5, 256GB, 8GB). Have already decided I need more RAM. 2 deals going on at the moment that I can’t decide between. Which would you choose?

Macbook Pro M1 (1TB, 16GB) £1650

Macbook Pro M3 (512GB, 16GB) £1709

I’m tempted to go for the M1 as doesn’t look like the M3 has many advantages that I can see? On the apple website it even looks like the screen is the same? Might get more battery life with the M3.

Thanks!
