I'm 6'6" tall. Ihave a 36" inseam. 25" frame fit me 34 years ago and same bike still fits me today. My advise to you is to get the largest frame you can find. Maybe a taller set-back seat post if necessary.
Check out the Giant Contend bikes. They have an XL frame size that might fit you. I looked at them but couldn't justify buying a new bike just to buy a new bike. There's nothing wrong with my 34 yo Peugeot--but I digress.
Back to the OP's dilemma. Go to a reputable bike shop and have a fitting session.
