F1 2013 Which Mod should I choose from these two?

F1 2013 The Game (Codemasters)
I am not talking about asingle Mod, as I know there is a special section for this, so please don't delete this post, is a question that may be of intrest to others friends.
I just wood like to know from people with more experience and more hours played than me, which of those two Mods "Ultimate Realism Mod" and "True to Life" gives more realistic and amusing drive experience, since they seem to be quite similar and did'nt understand the difference.
Thankyou everybody will reply
True to Life focuses more on the AI, where Ultimate Realism changes pretty much everything - damage, tyres, AI, times, handling, etc.

I think. I might be wrong.
