Got to agree 100% with TommyGun. I have, albeit briefly flown the DA40 (Avgas) and although it feels less like a powered glider than the DA20, it feels delicate compared to a PA28. I did not think it handled nicely-the ailerons were stiff. The performance was slightly better than an Archer but I believe the diesel version doesn't go as well, and I've not compared available payload. If you are a renter there is no advantage in cost.
Maybe it's an age thing but getting in a PA28 (or a Cessna) is like pulling on a comfy pair of slippers.
DO.
