The Pentastar is adequate, but thats about it. Its nothing special, and it works but its in no way fun, or enjoyable. I know the new 8 speed makes it a lot better then it is in my JKU, so I'm sure thats a help.Sorry, thought he was talking about the diesel. But yeah I think the 3.6 is a good engine, and much better than the 3.5, 3.7 and 3.8 engines it replaced. Not a torque monster by any means though but probably the best V6 engine I've owned in any of my vehicles.
