The Parkzone cub has a very strong following. Can't comment on the other.

If you want an RTF starter plane in the cub family, the one I would REALLY recommend would be the HobbyZone Super Cub:

HobbyZone Super Cub - $159
This is the only semi-scale plane on my list. I have not flown this
one but the flood of excellent reports leads me to recommend
it to new flyers. If you REALLY need a plane that looks like
something people would be in, this is the one I will recommend.
It takes the same Xport accesories as other HobbyZone and ParkZone
planes so you can drop bombs, parachutes and attach other accesories
to extend your fun. There has a steerable tail wheel so
you can effectively taxi the plane. Great for ROG launches.
