Other way around for me, I've experienced a lot of the original hardware but actually find the emulated experience more enjoyable. Things like save states, upscaled resolution on 3D games, customizable controls, online netplay for games that only had local multiplayer etc. Also in recent years some emulators have implemented features like rolling back one or multiple frames to do an input before you actually pressed the button, leading to lower input latency than the original hardware (can't remember the name of this feature at the moment).
