Sure, you may get a cute little sister who, while you may get to sex her up a few times, will probably grow out of it.
While on the other hand, you get a dedicated beautiful woman to do anything you ask at anytime, anywhere.
The choice is simple..."Master!"
There is still the fact that she will (I guess might) call you Onii-chan, even when she's older. That removes the lolifactor, but I still think it's better than just a maid. A few years of Onii-chan wincest is worth more than a lot of years of Goshujin-sama.
