These are being implemented in production on many a bank network...so yes,
they are plenty good enough. You will obviously need to test them in a lab
to make sure the features you need to implement don't have any bugs that
need to be addressed first. Overall I've had good experiences with them
though in a spine/leaf topology in major data centers.
I've also been implementing Arista switches as core devices outside of the
data center with some pretty great results, but you need to be careful to
make sure the features you need are available on the platform you want to
buy. As with Cisco (and any other vendor) there are some hardware
limitations where some features will exist on one platform, but not another.
