I suppose I'm qualified to answer, considering I have both.
E53 has Predator Ice (latest version)
E63 has AngeliBrigh (early version)
Brightness
IMHO, the AngeliBrights are a tad brighter (insignificant) * I'll see if I cn get a decent side by side pic this weekend.
Blinking
They
BOTH blink..
The AngeliBrights blink on both sides (it's been a while since I checked)
The Predator Ice blink on the driver side. I confirmed this tonight, without a doubt. They *may* blink on the right side, but the angle in which I was parked did not give a good view.
Ease of install
It's been a while, but the AngelIBright was very well documented and the install was uneventful. Getting to the bulbs on both cars is not an easy task (primarily the drivers side). As I posted in another thread, the Predator Ice were a huge pain in the a$$ to get snapped in place.
I am looking forward to the "updated" version of the AngeliBrights fo my E63. Blink free would be great.
The end result is too close to call, you'd likely be happy with either setup. I'm sure I'll get over it, but the fitment hassle is still fresh in my mind so if you asked for my recommendation, I'd have to say the well documented, well fitting Angelibrights would be my choice.
