Should I get the LG Pop or Samsung Flight from Rogers wireless?

Considering the price, features and the design of the phones. I know they are different levels of phones, one being more messenger friendly and the other more of a simplistic touchscreen. I currently have a Nokia 5800 but screen got broken. I quite enjoy this phone, but too bad I can't use it anymore. I am trying to find a new phone that I can use a unlimited mobile browsing plan on. I mainly use my phone for calling, texting and listening to music + randomly playing with it when I'm bored(this is where the problem comes in, the QWERTY board or a nice UI).
