Sharp or Dynex

[BloodHK47]

Hello everyone. Been wondering on getting a new flat screen and wondered about Sharp brand because currently I have a 40" Dynex (bought through Best Buy) and wanting to upgrade. Thinking of getting a 55" dynex 1080p 120hz for $750 but could upgrade to a 60" 1080p 120hz sharp for $1000. Is sharp brand pretty good and are the tv settings easy to adjust for tuning picture and stuff like that?

And also if there's a big difference between 55" and 60".
