The Real Book which is from Berklee School of music is one most players use but I like the original chords used on old jazz tunes more than the altered chords used in the books. It's all opinion anyway. I usually check out some charts for chords then alter them to sound the way I hear them. Hope that helps.....

Seeing I don't use fake books, generally speaking, I don't feel qualified to really elaborate more than I already have. But I can say that I often use changes in fake books as a guideline only. I may want to play changes that seem correct to me from an arrangement I like and use my ear to tweak them to what I want. I can only say that works for me having the sound in my head. I'm not always sure that my chords are absoulutely correct but if they work for me I use them. I am not a fan of a lot of altered chords and often use the "vanilla" changes because I play harmoniclly simple. I do that because that's what I hear and what i prefer. To each his own they say!
