LG ENVY 2 OR TITANIUM VOYAGER??

I'm 19 and in college and do a lot of driving, my mom has the envy 2 and it felt really small in my hands when i was driving and i'm really hesitant about the small screen on the front if i'm going to be going through my large phonebook looking for people's numbers to call. Anybody have any pro's/con's to list about the envy 2 or the titanium voyager? i'm stuck between the 2... how would the voyager work with car use... how pocket friendly is it seeing that it is much larger than the envy 2?

Thanks for the help!!
