It depends how good you are at doing attachments that hide the lace and how long those attachments last for you.
I can do a good hairline attachment but after a few days its good to have the option to have hairs covering the hairline if its started lifting and I don't have time to re-touch the front.

But its up to you. When hair is ventilated in a certain direction, its not set in stone that it has to lay that way.
