The biggest issue with aftermarket headlights is optics. The projectors on them are usually awful compared to own xenons. The other biggest issue is that I have yet to find any that at bi xenon. They all use the inner reflector for the high beam. If neither of those bug you, then it's just a matter of finding a set you like.the ones you posted look good, I'd run them if I could do a projector retrofit.
The bulb typically isn't the problem, even cheap bulbs and ballasts work fine. It's when you pair them with an awful projector lens that output suffers. A new set of aftermarket lights with a bi xenon retrofit projector is the way to go as long as you can reseal them properly.
polish your lenses and keep with 4200k bulbs. Those will be the brightest by far for output.
unfortunatley most of the aftermarket options for these cars suck, so OEM is usually the only route.
You could see if the LCI versions will bolt up, but they suffer from broken headlight adjusters quite often, or they pop off the lowbeam projector frequently. I see LCIs all over with at least one headlight pointed at the ground.
