As noted above I'd go with the strut lift (top hat) only. They make tall enough spacer to do that without using a pre-load spacer which will harshen the ride. Granted, doing a combo will accomplish the same goal, but I don't see the need for it.
Another option is to replace the struts with longer ones, such as Bilstein 5100 which is a very popular choice too. If you do that, I'd skip the top hat. Again, you can get a long enough strut to accomplish the goal with that alone.
I can't think of any reason to combine the two methods of lift unless you're going beyond the height available of one or the other. And in that case I think I'd look at a more complete lift than just a spacer anyway, because at that point you need to start looking at correcting the geometry of the suspension and driveline.
