I have access to a couple of Macbook Pros and a Linux machine with very good processors, but I do my hobby development all in an old Macbook Air. That allows me to see when my code runs slowly much more clearly. On an M1, everything just runs so fast you don't notice when you have a serious performance issue which is painfully obvious on the Macbook Air! I recommend doing that, though it does require patience waiting for things that are instant on the better machines.

I've always (well, since Pentium days at least) said you don't actually want your devs using top-end machines, at least for testing and debugging. You want them using the minimum target hardware. That way they'll actually care when the product slow on low end hardware, which will make it usable there and snappy on high end hardware. I've certainly caught a few accidentally-exponential style UI issues which were unnoticeable on a new workstation but very obvious on a slower machine.
