Moto-x 2014 comparison to Nexus 6 screen practical considerations topic

The Moto-x was on sale and I made a spur of the moment order -but I have been wanting the Nexus 6.

For a person with poor eyesight is one better than the other practically speaking? Text size and such? I am thinking I have buyers remorse and really want to order the nexus 6 and just return the moto-x when I get it.

I understand the spec difference, but many time practical considerations are more important.
