Sequel only works with SQL databases. DataMapper works with non-SQL databases. So if you plan to use a non-SQL database, you definitely want DataMapper. If you plan to use an SQL database, Sequel is a better choice, IMO. You may want to look at the Why DataMapper page (http://www.datamapper.org/doku.php?id=why_datamapper), for the reasons why the DataMapper developers recommend DataMapper. However, that page needs updating, as Sequel has optional support for an identity map, lazy attributes, and strategic eager loading. Unfortunately, I haven't put together a similar advocacy page for Sequel yet. The closest thing to it is probably the presentations I've given (see http://sequel.rubyforge.org/documentation.html).
