Everything has it's pros and it's cons: CoinMP is easier to use but OSI is more
flexible. Professional users may want to specify using other solvers (the
commercial PLEX code is said to be the top of the line nowadays), and there's
also GLPK (LGPL'd).

On FreeBSD we have packages for both CLP (using BLAS/LAPACK) and CoinMP (much
less optimized).

Also be aware that the CLP and CBC used in coinMP are very updated. My
suggestion is to try CLP (OSI is included) and if afterwards you still want to
go CoinMP I will respect that, of course.
