There's a long thread about these lights on the GolfMk7 forum. I don't think you'll find the direct comparisons you are looking for but they are certified in Europe which suggests a minimum level of quality. In my experience Osram makes quality products and I don't think these headlights are any different. Been running them for at least 6 months now. Never once had a flicker or issue of any kind. I have also not seen any condensation but I'm in Los Angeles and the car doesn't see much rain, general humidity or significant temperature swings. I go through a touchless car wash once a week though. The cutoff is clean and although it looks high against my garage wall I have yet to be flashed.
Coming from the halogens it's as close to a literal night and day difference as I could ask for. I don't regret a single thing about getting them. And that includes my misadventure with a deadbeat seller in my fool's errand to save $150 that involved a 3-month PayPal dispute.
Long story long for those who are bored, haha... seller, from France, sent a box and (in my opinion) purposefully didn't include a street number in the shipping address, which should've been copied directly from PayPal. Fortunately I had set up text updates for tracking and I saw when it got to my local post office and was marked undeliverable, to be returned to sender. PayPal policy is that if the recipient of the shipment fails to pick it up their right to a refund is waived. I went to the post office the day before they sent it back and picked it up, only to have received a box with a single broken halogen headlight in it.
Contacted the seller via email, PayPal, and the forums and was told their postman picked up the wrong box. After promising to send me my headlights they naturally stopped responding to all communications though they were still active on the forums. Opened a PayPal claim and included pictures of the literal trash I have been sent. Still I was told that I needed to send it back to France to get my refund, on my dime, within 14 days and including delivery confirmation. So I coughed up the money for expedited shipping of a relatively large box of garbage to France.
The seller never went to their local post office to pick up this box and on three occasions PayPal closed the dispute in the seller's favor stating that I never returned the "goods" to them there was never a delivery confirmation. After elevating my case 5ish times it was finally closed in my favor and I got the refund of what I initially paid, which equated to taking a $100 loss on shipping trash across the Atlantic.
By this time I had already ordered and received my Osrams from an actual vendor, which I should have done in the first place. Still worth it, lol.
