I thought it was a very solid show - new Nier announcement, new footage for Just Cause 3, Kingdom Hearts 3 and Deus Ex: Mankind Divided and word that they're working on a new IP (no, they didn't show anything from it really, but IMO it's good just to know they're still working on some new IPs). Oh, and an official US release announcement for Star Ocean: Integrity & Faithlessness with some new footage.
I'd rank the conferences like this (not having seen Microsoft's):
1) Sony
2) Bethesda
3) Square-Enix
4) Ubi-Soft
5) Nintendo
...with a bigger gap between 4 & 5 than the rest of them.
