I've driven base caliber with CVT and base Lancer with CVT. Both CVT's felt the same - Very horrible and sluggish. So I'd believe when someone said they're the same.
The engines are suppose to have as much power as the Mazda3/5 but it definitely felt much weaker (I think I was driving the 1.8L with 148hp). I suspect the transmission definitely affected the driveability of the car. Going uphill in the downtown area was terrible, the engine would drone loudly as if it were barely going to make it.
Funny about the bad fuel mileage comment, Dodge commercials for the Caliber are based on how fuel efficient it is.
It definitely gave me a very bad impression on CVT transmissions. I haven't tried other automakers' CVTs (like Nissan).
If you're ever going to get a Lancer, get their manual trans. Evo tranny is completely different, so that's apples to oranges. And Mitsu's fit and finish is 1000 times better than a caliber.
