what is implemented in the scikit matches the algorithms implemented in SPAMS. SPAMS implements more like positivity constraints for example. A real comparison in terms of speed and results has however not been done.
Note that for the positivity constraint we just need to modify LassoLARS and Lasso to handle it.
