i use a combination of both real and emulated, i would say that i use real more...
i have used WinUAE since 08.08.R8 and have never managed to get it looking quite right
i use emulation for stuff like snes and megadrive, as the real thing would take up too much space
i think for most people emulation is good enough to fill the "Amiga" gap, but for me nothing beats the real thing, plus i am a bit of a nerd, for example, i just pre-ordered and paid for... Skyrim on the Xbox 360, getting both the Collectors Edition and normal edition with the strategy guide... total cost £185
see what i mean
