Moto X or Galaxy S4

[JeffDenver]

If you're interested in specs then the S4 is the clear winner

Not necessarily.

The display is only 13ppi better than the Moto X...that is something no one will notice. Not even a tech nerd.

As for CPU/GPU speed, the Moto X has outperformed the S4 in several benchmarks. So I don't think that is clear either:
