The iPhone 5c was the "cheap" version of the iPhone available at that time, but it was discontinued in September of 2014. The Galaxy S7 was released in March of 2016. So, of course the 5c is going to be slower, have less storage and RAM, a smaller screen, etc.
A better comparison for the Galaxy S7 would be to the iPhone 7 or 7 Plus, since they were released the same year.
The main thing keeping me using iOS devices is the prevalence of malware on the Android platform. Over 99% of all malware designed for mobile devices targets Android.
That includes the supposedly "safe" place to get apps –– the Google Play store. It has been infiltrated several times by malicious apps able to get around their malware scanners, sometimes staying hidden for months and garnering millions of downloads before being discovered.
