I naturally prefer FotRSU. Way more merchant ships, way more airplanes, way more capital ships, etc... plus, if you want more duds, activate one of the three extra mods for that specific purpose, which can be found in the Extras / AddInModsPack folder (plus several others). Next full release will have harder AI escorts. We don't have to do a thing to the airplanes, unless you want more of those too (

)... TMO / RSRDC is really nice, don't get me wrong, but keep a history book by your side, and you won't miss much. FotRSU will not play the same way twice across a dozen tries.
