Either one is perfectly fine for your traffic load. You only have to
care once you get multi-gbit/s traffic (or over half a million pps) on
your system.
However.....
:choose the CPU with higher Frequency and less cores or for a CPU with

Higher frequency. Period.
Right now, network and PF processing is limited to CPU0. You want that
as fast as possible.
Additionally, you want as fast memory transfers (from CPU to RAM) as
possible.
That will give you the most performance.
