[Haskell-cafe] lost in generics

I need some help finding my way around the various generics libraries.

My usage scenario is -- at least to start with -- the ASTs of programming

It appears to me that there are two generations of generics -- earlier there
was generic haskell and strafunski
Now there is uniplate and kure (and syb? -- not sure of its generation...)

I get this impression because I saw a comment somewhat along these lines.

And also the very first reference link on the strafunski webpage:
viz http://www.cs.vu.nl/Strafunski/
seems to be dead. So I am wondering whether strafunski is still under
development or is it defunct?

The following paras from

The current status of generic programming in Haskell is comparable

 sound omninous :-)

In general my question is:  What is alive/active and what is alive/active
and what is -- um -- moved-on-from.
And of course which are easier and which more difficult to dig into.
