Since we were all at one point Amiga users with a real Amiga computer we recognize what gives the best experience which is, the actual hardware.
From a financial point it seems a emulator can do the same for a fraction of the cost and without worrying about limitations or hardware failure.
Personally, i would go for the antique hardware since emulators are only so good. This is especially true when you want to play games. Sometimes timing is an issue etc...
I want to get back myself right now, just did not see the perfect fit for me.
