I want to see with which ASes I am exchanging the most traffic across

I can better sell expansion of peering to upper management.

pmacct seems to be good at gathering Netflow, but doesn't seem to

for my purpose, however.
pmacct will do what you want and it's not particularly difficult to set
it up.
For example, you can aggregate data into a database using:
aggregate[in]: src_as,src_net,src_mask
aggregate[out]: dst_as,dst_net,dst_mask
Now you can issue SQL queries that tell you which ASes or prefixes you
send/receive the most bits or packets to/from.
