Aristocrat has the proficiencies that saves maybe two feats, and diplomacy skills. Probably wouldn't hold up under any optimization at all, but being able to use a reach weapon and heavy armor is going to whup the monk for a few levels.
The Aristocrat has a very solid skill list which opens up the possibility of being a pseud-face for the party, scout (with both listen & spot) and finally if we pumps some points into one or two knowledge skills we can get a nice bonus to combat through Knowledge Devotion.
The only problem with the Aristocrat (besides a lack of class abilities) is that the Marshal class is better in every way.
With that said though I could build a very legitimate Aristocrat build though given a little bit of time.
EDIT: Something like this might work well.
