I think you would have more fun with the pumper. The springer is harder on scopes. While pumpers are not known for pinpoint precision, they are fine for rabbits or cans.
Springers are often over sold when it comes to advertisments of speed. You have to know which pellet they are testing, or better yet just get the energy rating for the gun and you can roughly determine the speed with either weight pellet.
I have TX and HW springers, and even a USFT for FT competition, but when it comes to a rabbit, I reach for a vintage Daisy 880 pumper cause it is more fun.
Get them both!
