Only the name: Unithroid, Levoxyl, and Synthroid are all trade names for l-thyroxine (aka levothyroxine). The levothyroxine is the same in all the preps; dyes & inert fillers may vary.

Thyroid meds: The difference is mainly in the cost and availability. If cost is not an issue - thyroid meds are not expensive to my knowledge - take what your doctor prescribes. If the pharmacist tells you there are less expensive products they would recommend take their advice.
