Ios uptade over ota or via Itunes ? which one is better?

Hi All,

What is the difference between updating the iOS with iTunes vs OTA?

The problem is I have read some articles on internet that claims some users have issues (experienced lots of problems) after updating their ios over wifi (ota). this problem made me think that updating version via Itunes is better than ota.

On the other hand, considering that they both go through the same validation process before installation. Maybe, these processes are similar. However, I believe one of them should have a beneficial side due to not having the same connection type

Please tell me what is your opinion on this matter?

Thanks
