I've not used either of those tools, but here's some stuff that access does that I often find lacking in other tools:
1) You can copy a grid from excel, do a "paste as data" and access will automagically create a table, with the right data types and even pick up column names if headers are present.
2) You can view a table as a grid, similar to excel, and just start typing away to create data. You can do this before you even create the table to just start creating a table.
3) The drag / drop query builder is extremely easy, especially for things like cross tab queries. You can click "view as SQL" to then turn it into SQL if you want to tweak stuff. (I actually learned SQL this way)
4) foreign keys are made through a drag-drop interface "relationships"
5) The form wizard makes making forms really easy.
6) You can right click a row and delete the row. You can right click a column and delete the column. Any error messages are typically understandable and not cryptic.
7) All your data is in a file. A file which you know where it is, and you know you can click that file to open and see your tables and forms.
8) You can save queries which act almost like views / CTEs and in most queries you get a grid which you can just start editing data in if you so wish.
If anyone is unfamiliar with access I'd strongly recommending getting hold of a copy to play around with, it's how to do database right for end-users.
