There all powered by gcvideo code so they are all pretty much the same at the moment.
For plug in adapters, my opinion is Badassconsole > IBCTEK GCPlug > Eon GCHD > ZXP PnP 3.0. Badassconsole and GCHD has a molded plug which is superior to the 3D printed ones from the other two. Badassconsole is first in my list as there is some personal code changes to gcvideo and its firmware should be easily updatable. However, people has been waiting for years now for his product to launch. Eon and ZXP has glued case which makes updating the firmware difficult.
For soldered hardmod it's all a matter of preference. There's not many assembled options I'm aware of. GCDual would have a clean installation without removing the digital port. The DAC for gcvideo-lite I believe is now obsolete. Shuriken Video doesn't have that great of a mounting solution.
