Wire speed L2 in hardware is cheap, but layer 3 is not (and is typically limited to few k routes for campus type of switches). I have a Quanta LB 10G and a Brocade ICX 1G/10G/40G switches for lab use, which are hot and screamy but were cheap used. I would not trust software L3 implementations to not drop packets at high rates.
“ADHD and aggression” is a strange combination. It seems to assume that ADHD is correlated with aggression. I would not use such leading questions in a questionaire.
