Alpha blending is almost free on modern hardware, so I wouldn't expect there to be any performance difference. So long as you have a sane/natural order to draw your objects in, alpha is definitely the way to go. Then again, on really modern hardware you can use FSAA to get antialiasing for polygon edges anyway...
