I prefer to game on the original hardware where possible but Emulation is a real luxury for certain things, especially in Amiga world for setting up drives, etc.
If you can't afford a top of the range 060 PPC Amiga setup you can emulate a pimped out OS3.9 on any PC of the last 5-10 years at decent speed, of course there's no PPC emulation yet for Amiga but the 68k ports run like the proverbial off a shovel in WinUAE and the emulation is near to perfect these days thanks to Toni Willen still working on it.
You might think it strange but I also use my Amiga's to emulate other systems, the main ones are Mac (ShapeShifter as I don't own any Mac's here) and Spectrum. Of course I own several speccy's but not setup and ready to play, if I want a quick blast I can play via an Amiga and it's as near as makes no difference to the real thing as I'm playing with a regular Joystick and on a normal TV/Monitor.
As for shapeshifter, there are a lot of Games that work better than there Amiga counter parts, for example, Theme Park & Sim City 2000, I used to play Wolfenstein 3D a lot but that has since been ported to Amiga by Novacoder.
I must admit, when it comes to retro consoles I don't really emulate them on the computer at all, I have a couple of hand held devices that I use for portable emulation though. Mame I emulate on the PC when I want to play, but often I just head for the console ports. I do have a Neo Geo MVS for my Metal Sluggin' tho
Otherwise I have the consoles here and ready to play via my Projector or my new Sony PVM, for the rare and expensive games you can always invest in an Everdrive, I have one for my Megadrive and it plays SMS/MD and 32x Games
Strangely I still have a collection of over 50 games for the Megadrive! And over 150 for Snes/N64. A nice 40+ HuCard's for PC Engine, 100's of Saturn/Dreamcast,Mega CD etc. Oh and 75+ for Sega Master System, another system that emulates really well on the Amiga (using a CD32 pad)
Anyway, as you can see I enjoy both
