I have one of those, it's perfectly fine for everything I do. 8GB of RAM isn't a lot, but I've never run into issues with it not being enough.

The M1 and A18 seems rather similar, but I might be concerned that the integrated GPU isn't as capable as the one in the M1. I guess they picked the A18 because they make them and because the NPU much better and Apple cares more about AI than I do.
