Is there an existing comparison between pgManage and pgAdmin somewhere?

At first glance, it seems they serve the same purpose. Am i missing something? (besides the support for some other DBs - but pgManage states to target postgres primarily)

The main difference is that PgManage supports other databases too (although being mostly focused on Postgres support). Some new features introduced originally in Postgres get ported to other databases too (table structure editor and ER diagam tools for example)
