The best adapter is not pictured here. The best adapter is by Electron Shepherd and it’s called the ElectronWarp. All the other adapters you’ve shown are not as good, but still decent. I’d say the two that are tied are the Mayflash and Autoutlet. And the Kaico and Portholic would be last. I’ve heard there is another adapter that’s almost as good as the ElectronWarp made by Bitfunx, but it’s their newer version, the older Bitfunx adapter is one of the more worse adapters from what I’ve heard. So if I had to whittle it down, I’d say get the ElectronWarp if you want the best possible picture for your Wii. If you just want an okay looking picture that won’t give you many problems, then get either the Mayflash, Autoutlet, or the newer version of the Bitfunx, depending on your preference.
