HTC One or iPhone 5C?

Which is the better phone all around?

Both are $199 on two year contract for 32GB.

Personally I'm a mac user and have been an iPhone user. But I'm willing to try something new.

My concerns with the HTC include:

1. syncing music and podcasts

2. syncing browser tabs (something iOS7 can do with safari on mac)

3. How well does it work with a mac?

My concerns with the iPhone 5C include:

1. Potentially dated hardware over a two year contract.

2. Smaller screen

3. Not as much control as Android offers, which might be fun.

Answers, opinions?
