I know this is an older thread, but after usng the Haynes and looking thru the Chilton, I honestly suggest neither. If you plan on having the car for a while and doing any sort of upgrades/repairs, I suggest go for a Factory Serv Manual.
I bought mine one Ebay a few years ago for around $50 shipped, and it came with the electrical troubleshooting manual as well.
Really came in handy when I was rebuilding my transmission!
