The benefit of ODEPACK vs. LSODA is mainly that ODEPACK is a collection of solvers (A. C. Hindmarsh (1983) "ODEPACK: a systematized collection of ODE solvers"; in Scientific Computing, ed. R. S. Stepleman et al., North Holland, Amsterdam, pp. 55--64.) whereas LSODA is a solver. Some problems demand alternate approaches. ODEPACK sports the Petzold DASSL solver which is of proven utility for large chemical systems. LSODA however is excellent and quite useful.
