Depends what you're counting.

If you're counting requests from a client base that predominately supports EDNS0, pps ought to be very close to qps.

If you're counting responses sent to that same client base, then you might well see pps > qps if you're counting fragments as separate packets (seems probable).

If you're seeing a lot of TCP fallback, then you can expect the resulting handshake per q to cause pps > qps.

You never expect qps < pps, but the degree to which pps > qps depends.
