IBG gives you CDR and 60 armor, very efficient thanks to Nasus' lifesteal and bonus HP from ulti. Trinity gives you some HPs.

Utility-wise, it all comes down to your other items and your opponents. Against flashing, mobile opponents trinity is better, since they will ignore most of the slow. Against opponents that move a lot without dashing IBG is better.

If you have a good carry, IBG is better to peel for him and tank better, if you are the only real carry, you need TF to get to the squishes faster. If the enemy team is mostly AD IBG + Randuin or IBG + FH + Warmog will make you a huge tank, while against a heavy ap team you gain more from TF.
