I don't see the major difference in coming out of commercial with 150, 180 or 250 hours to be honest.
Maybe you have a little extra experience, but it's not like you're gonna go right to the airlines either way.
For my part, I'm planning on going right onto instruction now, and getting up to 800h + TT, so getting the extra hours while being paid for seems like a better alternative than racking up a few extra hours on a few cross countries here and there that I'm the one paying for.. Unless I'm missing something
