Is building a stroked 318 better than a stroked 340/360?

Back when I did my first stroker, I wanted to do at 318 and found out the pistons for a 318 (Back then) were a couple hundred more than the pistons for the more common 360 and when I talked to the machine shop, they had a 360 block for a 150 they were willing to sell me. And getting the extra cubic inches for less was a no brainer...
