Pros
Wells Fargo is solvent, has a conservative approach to their business mix and credit evaluation process, maintains a massive retail franchise, is intensely focused on profit, and is likely to stay in business for a very long time.
Cons
Wells Fargo is a bloated organization with too many non-producing staff members, large numbers of obstructionist managers focused on self-preservation, and promotes largely adversarial working relationships among its team members. Infighting is common. In addition to force feeding the most profitable banking widgets to customers, team members must engage in heavy self-promotion and finally be inducted into "the club" to advance. With a culture based on hard core sales and a pervasive sweat shop mentality, large numbers of customers are alienated and tend to be ignored unless they are likely buyers of new products.
