Here is my personal experience and opinion of WFG:
For the most part, they are a legit company. They sell all of the same investment products that more traditional companies sell. What I don't like about them is that they tend to just sell the same thing to every one of their clients without taking into account each individual client's needs or circumstances. This leads me to believe that they do not sell what's best for a client, but rather what gives them the best return on your investment.
Add to this that the underlying structure of the company is a "pyramid" scheme not unlike Amway. Each employee is encouraged to recruit other new employees. Each new employee gives a cut of his/her sales to the person who recruited them.
What this does is encourage new employees to be fast-tracked through training. The new employee learns whatever the minimum is to sell investment products and is then sent out to sell. Without really knowing how to direct client's money to best suit them, the employee just sells what they were shown during OJT, which is to sell a certain product that makes the company the most money.
Buy from WFG if and only if you've done your own research, possibly with the help of a truly trained professional, and you already know what product will benefit you the most. And then, only if because you want your commission to go a friend or family member who is WFG. Otherwise, just stick to traditional companies.
To quote Dennis Miller: "...of course, that's just my opinion... I could be wrong."
