I currently have the projector retrofit superlow 60mm buckets housings and halo kit (not yet installed)
but I had a buddy order a low profile 90mm bucket kit from Danyel and install his on his GT and I have to say that Danyel does high quality work they look great !
As far as a comparison there is differences but the overall end result is very similar and I believe you will be extremely happy with his set up! Danyel will be your best bet and you can always count on him for quality assurance!
As far as the projector retrofit guy unfortunately from what I know (not much) that headlight conversions is not his day job he was only doing those on the side. He is a real nice guy and very helpful but getting in contact with him is sometimes impossible.
