T vs SoD vs ROF?

[ChaosSlayerZ]

People keep saying that RoF is the most superior client.
But what are significant differences between T and RoF2? In terms of gaining and loosing?
I do understand that RoF gets access to bunch of extra expansions content, models etc. But what about something else that T doesn't have? Does RoF looses something T has?

How big is a difference between RoF and SoD? (again aside from actual expansions, zones, models)

I Have T and SoD, so I am not sure if I really should go out looking for RoF?

Thanks!
