I don't think you can make the decision without seeing shots of each in a car from face on, right or left three quarter and side on. The OEM Xenons flow with the lines of the car and are a coherent design. Both of these headlights look they've been scavenged from a parts bin and mashed into the housing.
Is it the cost or getting all the pieces of the assembly that is the problem? I might be able to help you out with parts as I have a wily supplier in Germany and I've tidied up the wiring looms a bit using Raychem heat shrink where I wasn't happy with the assembly.
You are correct in the fact that you need to see the lights from so many different angles. And you are also right in the fact that they are generic bits shoved into a Golf shaped moulding. And you are talking me back into the right direction........
The cost of the OEM kit does bother me and I won't spend silly money doing it. But at the end of the day going purely on the cost front I look at it as if I part ex'ed the car against another one with the lights I'd lose a lot more money than if I just fitted the darn things to my car. And also I'd get a few quid back from them when I sold up again which I probably wouldn't if I had a car with factory fit xenons. There is a nice looking GTI on a 59 plate in a London dealer that has xenons and a host of extras for about £21.5k. I'd probably get about £18k back on mine against it and yet at trade prices the two cars would only be about £600 to £800 different in value. So swings and roundabouts.
Getting the bits is the pain in the bum at the minute. There are numerous headlights on German ebay which are expensive and need all the bits added to them. There is a set of lights on UK EBAY for £800 that were £750 a few days ago(!!) which have the bulbs and bits with them, but I'm having difficulty in finding the correct BCM second hand. Id need this as my car is an early built and I have the warning light for the LED tails as well. So all in it's going to be a headache. Mike has been a diamond in helping me with what bits I'd actually need to buy and links to how to get at the BCM easily, so I could fit the things myself at least.
I'm pretty sure the only reason I want the darn things is because I don't have them! I almost never use the car in the dark as I tend to drive my ancient SEAT Ibiza GTI 99% of the time. The headlights are sh!te on that car but it doesn't bother me in the slightest!!
Anyone know a good shrink?

So all advice, suggestions, links and every thing else is gladly taken on board, digested, regurgitated and digested a bit more for the hell of it, and one day I'm either going to fit the darn things or just go and buy another car to give myself another load of things to tinker with. One way or another I just need a rocket up my arse!
The missus will moan like hell about the cost for a while but I'll buy her off by doing a few DIY jobs around the house I've been building up for an occasion such as this, or give her some money toward a holiday of something. She's used to it by now!
