This preferred brings close to 7% dividend.
And - I believe - parent company GS is not in danger of bankruptcy or reorganization - two (and only two as for today) killers of preferred shares.
As a result, you have a reliable 6.5-7% source of income - not easy to find today. It may go down for unknown to me reasons a bit - but your income will be intact.
Bought today 900 shares for $23.34-$23.36.
