To be honest with you, I have no idea, but I imagine they sound pretty much the same. They can only do so much with that low of a price point, and the components can't be too far different from each other. Inexpensive wall wart power supply powers a standard RIAA EQ curve. Cheap cases, cheap RCA plugs, resistors, capacitors and all that stuff in there.
I would consider your options depending on what your table comes with, yes. Lots of researching, that's typically something a smart shopper would do.
