If the keyboard is not important then this is not even a question
In terms of overall speeds
The Optimus V hands down.
On paper the Intercept has an 800MHz CPU (central processing Unit)
the Optimus V has a 600MHz main processor.
What makes the Optimus so much better is the addition of a dedicated GPU (graphics processing unit) and a dedicated data processor. Those two processors makes biggest difference in the world.
Optimus has slight more pixels. Optimus has a 320 x 480 screen compared to 240 x 400 for the Intercept, or a 60% increase in pixel count
And terms of the networkm the Optimus is also on a newer 3g network. Optimus has an EV-DO Rev. A radio versus an EV-DO Rev. 0 radio in the Intercept, its not much of a difference but it is slightly faster
