For a person needing basic phone capabilities, the Nokia 520/521 is better based on the price. For less than $50, I got the Nokia 520/521 smartphone, which is going to replace my dumbphone.
You can find the Nokia 520 on sale for $49.99 and the Nokia 521 on sale for $59.99 right now.
Use coupons and promotional gift cards to lower the price.
