Is the iPhone 5C still a good phone this year?

I'm using an iPhone 5C with 32gb right now that's unlocked but I also bought two iPhone 6 because I'm not on contract but with a prepaid carrier. I bought an unlocked 64gb and an unlocked 128gb one and when looking online I'm realizing that it might be stupid to keep the iPhone 6 since I could make profit when selling both phones. Would the 5C still be a good phone to keep this year and possibly next year?

What should i do with this iphone 6?

I have a sprint iphone6. I lost my job so I can't keep paying the bill. Yes I know my credit will go low but what can I do with the phone? Where can I sell it for parts? I understand that since its still under my account that it can't be activated again? Unless some tech savvy knows how to unlock but I need money now where can I sell it? Who will take it?

IPhone freezes when restoring?

I recently used iBackupBot to delete the large amount of text attachments eating up my iPhone's memory. I deleted all the little subfolders in the "Attachments" folder that contained the media, but I did not delete the actual Attachments folder itself. However, when I try to restore my iPhone with the restoration I deleted the attachments from, it nears completion and then the phone freezes and restarts. The phone itself is old and has been getting increasingly buggy (it's an iPhone 5), so freezing isn't uncommon, but it's strange that it can't even do a restore without having to restart itself. Could this be related to the deleted attachments?
