I like that it's easy to use, very simple for new users as well as advanced power user. It has everything you need from form design all through submission of data back into sharepoint lists or databases. The only thing i dislike is how slow some things can be at times especially when creating custom fields which do not have any defaults set up yet. Make sure your account manager knows about this because sometimes they don't realize its going so slowly until after you've spent hours working with them trying to find out what could possibly cause such lag. There are many different types of forms we utilize but one of our favorites is just a basic contact information type where people fill their info down once then click submit. This way if they forget something later they simply go edit it rather than having to start over again every time!
