Having cut my golfing teeth as a young lad growing up in Oakland, I'd say Lake Chabot over Tilden by a nose. In the late 60s, into the early 70s, Chabot was always better maintained. Tilden may have been prettier, but Chabot had greens you could actually roll a putt on and fairway lies w/o mud everywhere.
Two rounds I had at Chabot will always stand out. Eagling 3 holes on the front nine (3, 4 and 8 ) and somehow shooting a 45 for the nine. The card was something like this: 853 366 536. A quad, a triple, 4 doubles, and 3 eagles! The other was taking a power cart with my beginning golfer sister, and watching in horror as she lost control of the cart going from the 8th green to the 9th tee. She jumped out, the clubs went flying, and the cart was absolutely destroyed as it fell all the way to the bottom, a drop of at least 200 feet. Forever etched in my mind.
