Looking to trade an iPhone 5c for an iPhone 5s?

I have an iPhone 5c 32 Gb which I probably won't use that much memory. Wanting to do an even trade for an iPhone 5s 16gb black/grey. Is this a good trade or not so good? Any thoughts

Considering the memory swap vs. The fingerprint touch ID, it's probably very close. Maybe throw in a few dollars but pursue that. It's fine. Best luck.
