Are they very different ? Or can experience on one be valid for the other ?

It's been a while since I've used AIX, but I think AIX is closer to BSD Unix than to Linux. All are far closer to each other than they are to, say, Windows.

If you can get around one one Unix, you can probably get around on most others. On the other hand, System programming is pretty different between AIX, BSD, and Linux, because of Linux' monolithic kernel. Application programming is probably somewhere in between; the experience helps, but the conversion rate is not 100%.

Define "valid". If by "valid" you mean that familiarity with one OS will help you work productively in another, mostly yes (YMMV). I went from no Solaris experience to designing installer packages in 3 months. I keep an O'reilly sysadmin pocket guide handy for when something doesn't work - it has annotations for the common commands where significant differences appear between Linux, Solaris, AIX, etc.

Of course if you mean "valid-as-in-I-can-get-a-job", remember the HR rule. <bitter>Unless the applicant has years of experience on exactly the desired major AND minor release of THAT OS, the resume gets tossed</bitter>. Which is why so many people I know lie and become valuable employees.

Yes, that' what I meant. I have used Solaris for about 2 years and have played around with Linux. Because the commands look very similar on the face of it,
in my mind they have kind of merged. I don't have any experience of Unix on AIX. I just wondered about the similarities.

I guess some people might lump them together as belonging to the same family whereas other people who'd know one of them really well would get very offended.

As when comparing C# and Java.

That booklet looks handy.

It is sorta covered in the JavaRanch Style Guide.
