My vote is definitely Jackson 4fun for a great riverplay boat to progress with. more stable downriver then the star series, but you can still get after it in the park.
the fit, geometry, and rollability are night and day better then older boats, although most of us learned with those boats. I had a Wave sport EZG 60 (newer then the EZ...EZ front, ZG stern) it was a good boat but a bad fit for me and hard to roll consistently.
JK boats are really easy to roll. and stable, and yet still playful. exactly what a beginner wants, and still what I want as a 15 year intermediate paddler.... (Superstar & Superhero are my two boats. I really want a Zen river runner and a Rogue for Self support camping.... all JK boats... there is a trend with me....)
The Fun series is awesome all around playboat, but if you want to really feel safer on longer runs (Ark, Poudre, Lower CC, Rio Grande etc) .... might want to consider a Riverrunner /creeker like the Hero, Zen,Karma or LL Remix, Jefe, or dagger Mamba.
most folks eventually settle on a two boat quiver
layboat, and creeker or river runner. (until you can afford the specialty boats... i am not there yet either...lol)
