Depends what you want to do. If you want to play 68K games, yup. If you want to use the latest PPC apps, nope. With UAE on a PC you are limited to OS3.9. MorphOS 2.X has progressed far beyond that.
Indeed it depends on what you want. I have two machines with MorphOS, but UAE is much more convenient since I can use it everywhere. The result is that I rarely find myself in MorphOS, but mess around with AmigaOS3.9 almost daily. Sadly for MorphOS there aren't really that many native apps for around that makes it so much better than UAE and 3.9. Also there's lots of quirks with MorphOS that I dont fancy at all, luckily the compatibility is good enough for many of the old 68k OS components to work.
