Standard 5 is a Mexi 5 with 20 frets and a body more like a 4 string J. The Deluxe 5 is a 22 fret 5 like an older American Deluxe 5 body shape.
Unfortunately, Fender has muddied the waters quite a bit with changes in neck pocket and mounting patterns. (ie. 5 bolt and their contoured heel)
If you want more of a traditional body shape like a 4 string J, but with 5 strings, the Standard 5 is a great option. Of course, you can always bling it out too!
