Pretty simple question - which of these handsets is the better?

My sister-in-law is looking for a new phone to replace her rapidly failing Sony Experia.  She wants an iPhone but can't afford it yet, so wants to get a decent cheap phone to tide her over for up to 12 months.  She's found these two models at DSE for under $200, but wants to pick one that is reliable and usable.  She's a heavy txter and Facebooker, if that's relevant here.


I know next to nothing about handsets other than the iPhone, so while I can scout reviews and the like, I'm not an expert.  I'm hoping some people here who have either of these handsets can provide some views on whether they are good handsets, and worth the money?

Thanks
