Tools for library management?

[amabrok]

Thanks to this thread I discovered Yate and Metadatics. Until now I did all metadata editing in iTunes, but their editing interface continues declining. Many things don't work as they should. Now I got trial copies of Yate and Metadatics but find both GUIs a bit complicated and not extremely well organized. Nevertheless I'll probably stay with one of them. 

Which of the two do you recommend in terms of stability and iTunes integration? Thanks.

for me Yate seems more stable and reliable. a bit cleaner interface also, but i agree it is not that sleek and it takes some time getting used to it.
