That depends on your objective. With GPL license, all applications that use your library must be GPL or compatible.
With LGPL, all applications statically linked to your library need to be GPL or compatible.
With modifyed LGPL you can statically link proprietary applications to your library.
Because statically linking is often used on pascal programs, I would say this is the best option. Supposing of course you with to allow the use of your library by proprietary programs.
