New(ish) Chargers, are they any good?

I have an 06 Charger RT, and it's a good thing they changed platforms in 2011. My suspension has clunked even though I had rebuilt it with all brand new stuff just two days later. However, she runs sweet and smooth, I love the 5.7.

But my boyfriend's got a 14 Challenger SXT with the 3.6. I've driven it a few times and I really do like it. It's quick off the line, gets to speed quickly, and it's been a great engine. He drives that thing hard and we've driven it from Washington to Nevada and all he's ever had to do was oil changes at 5k intervals and spark plugs at 100k. Another thumbs up for the 3.6!
