It is slower than MyISAM, but you get ACID in return. It performs on par
with MySQL storage engines with similar features. In the end, it depends
whether you need the speed or robustness/stability. Both MySQL and
Firebird have it's use.

The part saying it crashes is nonsense. I've seen much more MySQL
crashes that Firebird ones, and I use Firebird for 90% of my projects.
