"Now with having that said what advantages does a "pattern craft" have over my 3d profile plane? can they hover?"

There are actually a fair number of sport/3D arfs that can fly pattern reasonably well on low rates and also fly 3D on high rates. Aircraft like the Lanier Razor 3D and the Model Tech Twister 3D ARF are built like pattern ships, but with 3D-sized control surfaces.

I often compare pattern flying to skateboarding or snowboarding in a half-pipe, with the pattern flyer's half-pipe being the "flying box" that they stay in. The pilot will take off and do a wing over or stall turn, enter a pattern manuver, then fly up the other side of the flying box, turn around and enter another manuever. It's very graceful and quite fun to watch.

With a hybrid pattern/3D style ARF, you could learn to fly the sportsman or intermediate pattern routines and still have a 3D capable plane as close as your high-rate switch. If you moved up in competitive levels, you'd likely want to get a dedicated pattern ship of some kind. For the non-competing sport flyer though, many popular models can do both well:

Lanier Razor 3D
Model Tech Twister 3D
Great Planes U Can Do 3D
Goldberg Matrix
Sig Mayhem
Hangar 9 FuntanaS 3D
Hangar 9 Showtime 4D
Model Tech Formula 3D

I'm sure there are many more models capable of both 3D and pattern flying, but the above list will give you an idea.
