What’s the best balance of authenticity and convenience for SNES/Genesis on a modern

[Adam87]

I'm thinking about buying a retro gaming console to replay some classic platformers and RPGs from my childhood, but I'm torn between getting original hardware, which seems expensive and finicky, or a modern emulation box. I'm worried about input lag on emulators ruining the experience for precise games. For collectors and enthusiasts, what's the best balance of authenticity and convenience for someone who just wants to reliably play cartridges from the SNES and Genesis era on a modern TV without breaking the bank or dealing with constant maintenance?
