Merge modules (.msm) can be used by any MSI building package. They are the Windows Installer version of libraries. See http://msdn.microsoft.com/en-us/library/aa369820.aspx Wix Libraries (.wixlib) are only usable by WiX AFAIK. See http://robmensching.com/blog/posts/2008/10/10/What-are-.wixlibs-and-why- would-you-use-them
If you're building libraries for internal use & you're using WiX everywhere then wixlibs are probably better/faster/easier than authoring merge modules. If you need to share stuff with 3rd parties or make it publically available you may need to build merge modules if your users aren't using WiX to build their MSI's (or you could be nice & provide both).
