I'm not sure of the differences, SRS but LibreOffice is the one bundled with my Linux distro. It would meet most (how do you quantify) needs but I'd be tempted to suggest forget it if you really do want Access. I cursed that one back in 2.0 but have used it since and last time after a long break on the trivial ICT course I attended. I know my thinking has a Linux bias and would be thinking of at least cross platform alternatives like the Libre/OpenOfics things but I'm not aware of anything in that line that (at leat to me) would allow a relational database with forms, etc. with the ease you can do with Access.
