I don't think that MYM will be better or even as good as FIM because it's unlikely to have the same charm or wit that FIM gave us.
Not to mention, knowing that the ending of FIM had to be overridden for the premise of G5 to exist could consistently leave you feeling disappointed.
I think the best thing to do is to hope that G5, or at the very least the fandom, will be decent.
Also, we can hope that the future of the franchise will be decent enough to keep it from becoming less than decent.
