I just finished downgrading today and I have to say, I don't really miss the online part as much as I thought I would. But I really wanted the wider tracks and better stance for my cars because it really looks that much better. So for me there was no debating on whether to downgrade, although to anyone who decides to do it: Plan enough time for it. Depending on what kind of connection you have this might take hours, if not days. In my case I took about an hour and a half (25k, wired). Unless you reeeeaaaally want to play online, there is no point in installing the 2.12 update. With all the hybrids I can create, the game has basically endless replay value to me, or at least until GTA V and GT6 come out. Then there will be no more life for me, I'll be tied to my PS3 day and night haha
