Is there any easy example of a finitely generated group with a Cantor set of ends that is not quasi-isometric to a finitely generated free group?
Thanks in advance.

The free product $\mathbb{Z}^2 \ast \mathbb{Z}$ has infinitely-many ends, but is not quasi-isometric to a free group: furthermore, it is not hyperbolic since it has $\mathbb{Z}^2$ as a subgroup.
There is a considerable literature on the subject, see the paper of Papazoglu (who is usually Papasoglu) and Whyte.
