I use the TSC for high precision timing, and turning TSC ticks into nanoseconds requires interpreting model specific registers, so my timing code would need AMD specific patches to work properly on those processors. Not necessarily a deal-breaker, but it would definitely be an annoyance for me if I did decide to switch. Probably not super relevant to scientific computing or ML though.
