Wanted: info on UNIX for IBM PC/AT and compatibles

[PETITPIERRE Dominique]

I've heard about three Unix System V like implementations for IBM PC/AT &
compatibles:

Venturcom's  VENIX SYSTEM V.2
Santa Cruz XENIX Sys V.2
Olivetti's System V for it's announced M28

What are they like, what are their advantages/drawbacks?
Has anybody had good/bad experience with them? Any benchmarks?
How standard are they (uucp OK? cc OK?)?
On which compatibles are they really running/ what would be the delicate point?
Where can I buy them in Switzerland or Europe?

Any pointers on literature (reports,articles etc)?
Is there any other serious UNIX implementations for IBM PC/AT & compatibles
(BSD 4.2 ? don't laugh, that would be so wonderful, a little dreaming doesn't
harm).

Thanks in advance for your help!
