Which is better? OS 4 or Morph OS . . .

[AmigaMance]

 I can't comment which OS is better since i have an Amiga 1200 and i have only tried MOS. Imho the biggest weakness of MOS is its desktop, Ambient. Workbench 3 (with mcp installed) is much more pleasant and productive enviroment for me, even if it looks uglier. I don't care about that.
 I have 2 speed related questions:
Which OS is generally faster? and
Which has the fastest 68k emulation?

@AmigaMance
You could run Workbench on MOS, if you prefer it over Ambient, see AmigaWBOnPegasos.readme

 Ok, i will try it.

I haven't seen reliable benchmarking done on the identical hardware, so I can't comment that part. If run on their native systems Pegasos II and AmigaONE, MorphOS and Pegasos II win for sure, since Pegasos II with G4 is faster than any AmigaONE available.

 You're right. My question should have been: "Which OS runs faster on a classic?" But, i guess, only a OS4 beta-tester with a Amiga 1200/4000 can answer that.

To my knowlege only MorphOS has transparent JIT compiler available for general public. So, MorphOS 68k emulation is faster.

 I'm getting a little confused here, probably because i'm not familiar with the new systems. How AOS4 is able to run 68k code without a 68k emulator?
 Here is an excerpt from the AOS4 feature list:
"Just in Time (JIT) 68K emulation
Dynamic recompilation or JIT compilation is a technique whereby (in this case) 68K machine code is translated on the fly to PPC machine code which is stored in a temporary buffer to avoid recompilation each time the recompiled code is executed. All 68040 instructions including FPU instructions are fully emulated. Even on a lowly 603e@160 Mhz the recompiled code reaches and in some cases surpasses the speed of a 68060@50 Mhz."

 Excellent!
