Thanks for the posts.
The guardian policy i'm looking offers benefits for life, not just until 65, you get certain percentage of your benefit based on the age at the time of your disability. Its starts dropping off at age 40 or so. I'm only 29. The standard policy offers a higher monthly benefit, for the same price.
Both have riders for increased coverage later. Both have COLA adjustment riders. I've have an acquaintance (not a physician) who had to file for disability and had a standard policy. The said the customer service for her claim was amazing. Didn't dink around, hired lawyers to get her SSI disability processed. Quickly paid back payments after her claim was processed.
