I don' t agree that every time the paid articles provide update research because there are many good journals which do that and it is freely access. Taking money or providing free access to the article does not indicate the qulaity of research but depends upon the organization from where the journal is published.
Yes,it is the best way to ensure you get up-to-date research information rather than finding free research information which could be either not up-to-date or unrealistic to the environment and culture of area of your research work e.g there is a big cultural difference for people from Europe to people from middle east.This could apply in case of saying that all people from Arab countries are Muslims without giving consideration to population and religious mix differ from one Arabic country to another.
