Which phone


I'm in Canada with wind mobile and I want a new phone. I can get the nexus 4 on the tab for 250 or I can get the RAZR V for 100 also on the tab. Theres other phones on the website shop.windmobile.ca but those two are the only ones that stand out to me. I've also been thinking of buying a phone unlocked. So far I've looked at the Xperia T and some Blu phones (I like the FM radio) but I want to stay at around $300. Whichever phone I get I want to keep it for the 3 years so I don't have to pay more. I don't know a lot about phones so thanks for your advice.
