The TL projectors have the solenoid at the bottom which make mounting them more challenging. You'll most likely run into clearance issues with the solenoid.
But the TL projectors have pretty good output and a nice cutoff line. If you put some clear lenses on them, they perform even better. The RS6 bixenons are also pretty good.
If you go with a bixenon projector you'll have to wire the HID ballast to the low beam, and then wire the + from the high beam to the + of the solenoid.
Here's a pic of my almost completed retrofit for my other car. TSX projectors in the top, TLs with clear lenses in the bottom. You can see that I had to cut around the bezel to make room for the solenoid.
I think TSX projectors would be easier to retrofit on the Legend. I have A4 projectors on my Legend, small pic in the sig.
