I don´t know all the 1st/2nd party franchises from Sony and MS, so I´ll be missing a few.
Anyway, we have from MS:
- Halo franchise
- Gears franchise
- Forza
- Fable
- Crackdown
- RARE titles (Kameo, Viva Pinata, BK Nuts & Bolts)
From Sony:
- Ratchet & Clank franchise
- Uncharted
- LittleBigPlanet
- Resistance franchise
- God of War
- Gran Turismo
- Team Ico titles
Like I said, I´m sure I´m missing some IPs.
Anyway, I like them both, but I like Sony´s 1st/2nd party portfolio more.
What about you?
