For a novice needing the best all around service manual I'd also vote for the Motor's Manual. I started doing serious car work when I was about 12 or 13 and the copy my dad had was the bible. Soon after I was given the 1960 version by a guy after I changed the clutch in his 55 Buick. He said I'd probably get a lot more use out of it than he would, and I certainly did. They had great information on troubleshooting and tune ups, and as I got a bit older I rebuilt 3 speed Chevy transmissions with nothing else.
When I got back from the service I bought a 1970 Chilton's manual. It was very impressive, over 3" thick - and was a great disappointment, lacking much of what the Motor's Manual provided. I have found Hayne's manuals worthless. I remember wanting information on how to do some detail work, and the instructions would start out - first remove the engine! I kind of needed the 35 step process that resulted in removing the engine.
Of course the Chevy Truck Shop Manual covers everything, including how to replace window winders, glass, align body panels, suspension, etc - and you won't find that anywhere else.
Another opinion for what it's worth.
