Nothing makes them particularly special.
However fringe systems on the edge of the bubble take your pick will offer up missions paying millions.
I use FEHU because it has fed aligned missions which helps rank grind.
Andy robigo because they are neutral missions with delivery in fed space and more frequently I get bounty kills when interdicted.
And robigo you can stack up to 30 to 50 milLove worth in a few bulletin board refreshes.
I don’t recommed taking more than 10 at a time as the interdiction rate and potential loss stack up
