Rectangular versus fancy design speakers?

Many of us grew up with basic rectangular speakers which seemed to work fine. And as I look around the landscape I see lots of higher quality rectangular speakers that look very nice.

I like the pretty speakers with their stylistic designs.

Right angles are a bad thing with curvy surfaces being better for sound, so they say.

Does it really matter and I would think a rectangular speaker which probably has more of a budget to spend on the quality of what goes on inside versus spending so much money on the looks may be better.

Any higher-end rectangular speakers worthy of a recommendation?
