I dont want to turn this thread into a MorphOS or AMigaOS 4.1 thread, but on the same hardware with one running and switch to the other MorphOS blows away the other in all areas. Moving to a Pegasos II and running the latest OS4.1 and MorphOS is also the same in that area.
Setting up OS4.1 Classic using the new Amiga Forever 2016 isnt that hard. Its well worth doing and comes with everything you need. If you are handy with scripting you can set the machine to boot directly into the environment with little effort.
I can vouch for that too, MorphOS on my Pegasos II runs rings around OS4.1FE performance wise, it's also more stable and more compatible with 68k/WarpOS/PowerUP software too. The main exception to that being Octamed which doesn't work on MorphOS.
Both are great fun though.
OS4 on WinUAE is surprisingly fast, it'll be even better once it can use the accelerated UAEGFX P96 driver instead of an emulated Picasso IV.
