Yes, InnoDB tables are query-wise identical to MyISAM tables. You can also
mix different table types in a single SQL statement, for example a join.

In performance there is some fluctuation due to different optimizations.
Also, InnoDB tables take more disk space, and COUNT(*) of a table is slower,
because InnoDB does not store the row count internally.
