I have noticed during early stages of seedling/clones growth and up through veg the square buckets are great to really pack them under the lamps. However, during flower you may need the space between plants so the expensive square buckets may be a moot point. An expensive moot point at that.

Squares are hard to find, even at the Hydro stores! :wtf:

But I agree with Ocotillo, unless your planning a SOG style grow it doesn't matter round or square.
