There seem to be two options so I am curious which one is better.
A: "Mayflash SS Sega Saturn Controller Adapter Converter for PC" + original vintage SEGA Saturn Controller
B: "MAYFLASH MAGIC-S" + Saturn Style controller made by Retro-Bit
I have so many questions.
1.) Are these two methods even correct like this?
2.) Which method has less input lag?
3.) Regarding method B - There seem to be different "MAYFLASH MAGIC-S" devices. Which one exactly is the one I'm supposed to buy? (link would be ideal)
4.) Also regarding method B - I already have the black wired Saturn style controller by Retro-Bit that's compatible with PC and the Switch (just to be clear, the one I have is called "Retro-Bit Official Sega Saturn USB Controller Pad (Model 2) for Sega Genesis Mini, PS3, PC, Mac, Steam, Switch - USB Port (Black)"). It has no home button or anything (so not ideal on the Switch), just the same buttons as the original Saturn controller. Is this the correct controller I would need for method B?
Hope you can help!

Thank you.
