Realism is in the eye of the beholder.
The game mechanics of RFB are very realistic. That is their goal and they succeeded. It's a very good mod.

TMO on the other hand takes some liberties with pure realism but you will find that you need to play in a more realistic fashion. Also much more dangerous escort AI. I use TMO the most.

As far as eye candy goes both are very good.

Add RSRD to either and you have very a real campaign layer with all the big battles and true convoys.

Haven't played FOTRS yet.

Radio files need to be downloaded separate. They are really big so have some hard drive space.

JSGME makes swapping mods easy so you can try both or get MultiSH4 and play both at the same time.
