chrysler 3.5 V6 ??

well I guess that I started a small fire with this topic...sorry To add insult to injury . Are any of the modern Chrysler V6 engine say from 2006 to present day, any good ? I'm thinking of buying a used car (don't know year, or model yet) chances are that it may have a V6. For that matter what about the 5.7 hemi?
Also the automatic transmissions that were used on those engines...Like I said I've been out of the auto repair business for so long , that I have NO IDEA what is good/ and what is junk any more.
