I was recently in the same situation as you and I went with the DEPOs (

I got the V1 since I like the yellow OEM AE look. It definitely is dimmer than OEM, but as long as you're not in direct sunlight, you can see them. You have the option to keep the low beams halogen, which means you'll basically be running the H7 bulb behind a projector. I haven't seen any myself, but I feel like the V2's will look odd with halogen bulbs since the AE are LED.
Keep in mind, if you end up getting the DEPOs, you'll have to get your car coded to run the AE as DRL. If you don't, both your the stock halogen DRL and the AE will light up.
If you get the HID kit, you have to purchase the error module to get rid of any codes. I haven't had any errors with the HID kit.
I bought them from MB also since they were local. Took a little longer than expected, but in the end, they got me what I wanted.
