Me - I'm undecided.
On the one hand emulation offers you virtually (no pun intended) any Amiga with greater speed, screen resolution, RAM, range of peripherals, etc. All this running on your PC - requiring no other equipment/financial outlay.
On the other hand, a real Amiga produces a much richer display, smoother scrolling and character - that despite being defined by its quirkiness/inadequacies/WHY - is simply charming.
One upshot of emulation is that it opens up the Amiga world to non-Amiga owners (let's assume they bought the ROMs). Once having had a taste of a virtual Amiga, they then may go on to buy Amiga hardware to live the experience for 'real' - increasing the Amiga userbase - which can only be a good thing! :-)
