What does 64-bit mean in the context of smartphones?

I realise that 64-bit is obviously better than 32-bit, but what does that actually mean on a phone?

Or should I just accept that it's better? ;)

32-bit is unable to have more than ~3.5GB of RAM.
64-bit will be faster with 64-bit optimized application, but not twice as fast. Only moderately faster.

Accept that it is better. Sometimes. Maybe. http://en.wikipedia.org/wiki/64-bit_computing
Few mobile apps are optimised for 64-bit ... and honstly?

I used both the iPhone 5s and the 5c. Frankly: at this stage there's not much between the two.
With future OS and apps updates all that may well change.
