Brotherhood got super stale towards the end and I couldn't wait to leave it behind and play Revelations. Parkour, modern day and historical story, plot pacing protagonist are better in Brotherhood, while III has a better setting, combat, database writing and the modern day missions were quite fun. Both are good, but I'd give the edge to III as Brotherhood got boring after 40 hours while III didn't. The story itself in the modern day in III was awful, and Desmond looked like a malnourished ghost.
