Have 2 offers on the table... Having a hard time deciding which one Id rather have

Not necessarily rebuilding, just clearing some cap space and trading a solid vet (Dan Haren) and looking to build my fairly thin farm up. Dont really have an specific positional needs as my team should contend and be in the top 7-8 teams in a 20 team league.

Package 1:

P Carlos Martinez

OF Oscar Taveras

P Lance Lynn

OF Charlie Tilson

Package 2:

OF Wil Myers

P John Lamb

P Kelvin Herrera

C Cam Gallagher

Leaning towards package 1, as it seems to be the superior all around package. However, Im not sure I can pass on getting someone like Wil Myers. Someone fairly close to the majors with tremendous upside. But if people think Tevaras could be just as good as Myers, then I would go with package 1. Not hell bent on getting close to major league ready guys, but its just hard to pass on someone so close to the majors who should be able to jump right in and be a safe bet to contribute.

Thanks in advance for any advice. I know these types of threads get a little annoying.
