You ropinion is true. SFC's make the most difference.
The KB still mounts as you described, but a quick alignment check is easy to most people than drilling all the extra holes other brands use to mount at the strut tower. The KB is a very nice piece.
The EvM unit is the bear. It's a 6-point brace and requires drilling 8 holes, adjusting the height and width and relocating some stock parts. It's very nice, but installation takes forever.
