Most .90 and 1.20 sized airframes are more expensive to outfit, but generally easier to fly than smaller planes. The size of your aircraft is often determined more by the size of your vehicle than your talent as a pilot. Large airframes are easier to see, more stable in the air, and less succeptible to wind than smaller airframes.

If you're interested in trying a great sport/pattern plane, take a look at the Great Planes Venus 40, Venus II, or Phoenix SeaBee ARFs.

The Phoenix Seabee is probably the hobby's best kept secret at $99.99; available from Tower, it's an extremely fun airframe for pilots who've mastered their low wing trainer and want to explore aerobatics further. It flies very well with a ball-bearing .46 2-stroke and is easy and straightforward to assemble.

The Great Planes Venus 40 and Venus II are two more great choices for an introductory sport/pattern plane with great flying characteristics. I would choose the Venus 40 over the SeaBee if you're certain you'll enjoy precision aerobatics and you want to invest in a top-quality ARF. I would choose the Venus II if you're certain you'll enjoy precision aerobatics and you want a larger airframe to fly as well.

Obviously there are dozens of fantastic choices for pattern aircraft on the market, I'm simply mentioning three of the most readily available ARFs that come to mind. The SeaBee is a terrific, inexpensive ARF that would be a good choice for your next step up in airframes. The Venus 40/Venus II ARFs would be excellent choices as well, with the Venus II giving you a chance to enjoy a larger airframe.

Good luck and good shopping!
