Decent alternatives to Sony xperia sp?

I'm looking at changing my windows phone to an android phone, I was thinking of getting a Sony xperia sp until I read about the terrible Wi-Fi connection this phone suffers from, any suggestions as to any other phones with similar specs and similar price range I could get? No iPhones or Samsung s4 suggestions as they are too expensive.

Nokia Lumia 520

Huawei Ascend Y300

HT Desire C

Here are some links first you see the features then you decide.
