Depends on what brand and size Edge and what brand and size Extra. And what the control setup and CG is.

All things being equal, a good flying Edge is easier to fly and land and less squirrelly than a good flying Extra. (Edges and Extras are usually not squirrelly though. That description fits CAPs and Giles better.)

Put your Extra together right, KEEP IT LIGHT, and follow the instructions on setup and it will fly fine.
