Hi! I've been thinking about growing my comic book collection these holidays, and I'm getting really interested in Batman and Robin's dynamic. The question is: should I read Morrison's run (with Grayson as Batman) or the New 52 Tomasi's one?

I really enjoy Morrison as a writer but I've only read Arkham Asylum, Batman and Son, The Black Glove and R.I.P. so, should I buy Final Crisis too if I wanted to fully enjoy his run? However, the New 52 are also growing on me lately (I'm about to buy Endgame and Geoff's run on Justice League); and maybe Tomasi's B&R would be a better choice then.

I'm really confused about which one should I start with, so thank you for taking your time to help me!

Edit: I'll definitely go with Morrison's run first all the way to Batman Inc and its conection with Tomasi's Batman and Robin. Thank you so much for your help, I should've asked you before!
