Delphi <--> Pervasive SQL 2000 (Btrieve 7.5)

Hi,  

Anybody with experience in the environment Delphi 5+Pervasive SQL
2000(Btrieve 7.5)?  

The environment of the app is C/S with 10/15 users. It is necessary to have
experience
to be able to evaluate the performance, the level of security, the power of
the SQL,
the stability, the recovery capacity in front of breaks,...  

The price is an obvious advantage in front of other databases, but, which
are the disadvantages?

I would thank information of a document with the comparison Pervasive vs.
Interbase or MSSQL.  

Thanks in advance,
