You won’t be able to use the classic flap as a crossbody if you’re 6ft. I’m 5’3.5” so a lot shorter than you and it only just looks okay as a crossbody. If that’s important to you go for the Coco Handle. I think the strap is longer. I don’t own a Coco Handle but I believe they are fabric lined whereas the classic flap is leather-lined. The CH is a lot less expensive than the classic flap so again if cost is a factor in your decision, the CH would be a better choice. I have the Trendy CC. Have you considered this option? Leather lined, very luxurious, and looks very similar to the classic flap. It has a top handle and a chain strap so you can use it crossbody like the CH. it has a gold bar on the top that says Chanel so you may or may not like that.
