Scott's is more detailed.
The IENI book on tasting is very poetic, but mostly a repeat of the standard coffee cupping methods available on-line; the espresso Italiano book is mostly the rules for a cafe getting their "Espresso Italiano" certification.
Scott's book gives a lot of information on extraction and packing techniques. All of this is actually more useful to home baristas than pros, since some of the techniques are on the slow side. The machine and grinder info is also detailed and fairly up to date.
I was going to do a follow up on the introduction to espresso article; but Scott's book is better than anything I could have produced.
