I think both are very different in purpose and function and it is like comparing apples and oranges, but one may support the other.
The main function of your SFI co-op is for the distribution of signups to participants of the co-op, who are also your PSAs, while the purpose is for team building.
On the other hand, the main function of a blog is to create awareness either for yourself or your business, so you are either publishing your business as in your case or publishing your self. So depending on how you want your blog to function, blog can be used to promote your SFI business by using it to generate signups, and to train, guide and support the members of your team.
As you can see from the above, SFI co-op and Blog are different, but you can use your blog to support the success of your SFI co-op if you decide to direct all or some of the signups generated by your blog to your SFI co-op.
Having said that, the one that provides the most value will depend on how you want to run each. If you intend for your blog to be for recruitment, training and support of your team, then it obviously provides more value than SFI co-op. This is because SFI co-op does not generates signups by itself, but just a receiver. More so, a co-op cannot perform other functions a blog does.
You may do without the co-op if you like any way, because the signups you may generate from your blog can also be directed to members of your team by reassignments.
To conclude, I am not suggesting that a co-op should be dispensable, but that there are other ways to direct signups to your team without it because its only function is distribution.
