If you want your app to use more than one 'backend', not just FB. If you are
only developing for a single 'database' a native component set is always
better IMO.

Price is the only one I can think of, and only then if you plan to stick to
current versions of FB.

Well, there is no dbExpress driver for FB that comes with Delphi, AFAIK
(although there is one available from, so the free options
are ZeosDB or IBX. I have not used Zeos, so can't comment, but I would not
recommend using IBX for any new development.

IBO has a 'trustware' licence, which basically means "you don't pay, till you
get paid", and I belive FIBPlus has something along the same lines. I would
personally go with one of those.

The minimum, you won't be able to use any FB new features/datatypes/API's
etc, the maximum, they won't work at all.
