My experience:

G5 ID 11,2: supported Linux + MorphOS ( partial official support, in real all important works )
- CPU with SIMD (AltiVec), 2 - 4 cores, 2.0-2.5 GHz, 1.9 MIPS/MHz/core
- RAM max 16 GB DDR2
- 4x PCIe v1.0: x16, x4, x8, x4
- 2x Sata 150, 1x ATA 100 for DVD
- this Mac is very fast, very power hungry and often picky with PCIe cards. Installation of linux is much more difficult there ( not base system, but proper booting )

AmigaOne X1000: supported Linux + AmigaOS
- CPU with SIMD (AltiVec), 2 cores, 1.8 GHz, 2.2 MIPS/MHz/core
- RAM max 16 GB DDR2
- 5x PCIe v1.0: x16, (or x8 +x8 ), x1, x1, x1
- 2x PCI
- 4x Sata 300, 1x ATA 133
- X1000 is fast, but slower than G5. Has much lower power consumption. My X1000 has problems with compatibility of RAMs. I can place only one stick per channel, i.e. my RAM capacity is halved. Even if CFE firmware has many flaws, is much more variable and friendly than Mac OF.

I have no experience:
AmigaOne X5000: supported Linux + AmigaOS + MorphOS
- CPU no SIMD, 2-4 cores, 2.0 - 2.2 GHz, 3.0 MIPS/MHz/core
- RAM max 64 GB DDR3
- 5x PCIe v2.0: x4, x4*, x1*, x1*, x1*
*) total 4 lanes shared via PCIe switch
- 2x PCI
- 2x Sata 300
- According to specs, she is probably very fast in non-SIMD tasks and you can use three OSes. Only PCIe switch causes some latency on bus.

In 2020 I made some performance comparison here.
This comparison is obsolete now, we have many new drivers. And also have in mind, that MorphOS is in most cases more effective than AmigaOS, and it is reflected in the benchmarks.

My general opinion is that Powermac G5 2.5 GHz is faster than needed for MorpOS, iMac G5 is not good and X1000 is fine (but not for MorphOS, of course).
