What is the best mobile software to use: iOS or Android?

iOS easy but limited in terms of free softwares, while android has lot of free softwares to install and is highly customizable due to open source nature

It depends what are you looking for. iOS is easy to use cause have less customisation while Android gives you more flexibility with customisation. IOS has more security than Android as it doesn't now allow you to download anything on the device straight from the internet same android. For example you cannot download music from iPhone straight should purchase from iTunes or download it on the computer and sync it on the phone using iTunes.. Android allows you to download music straight from the phone directly to the music library this could have viruses attached to it thus needs to download on the phone antivirus application.

Both are very stable and well developed mobile operating systems. Androids can be customized more easily. iOS phones (or iPhones) are generally more expensive.

IOS is a best mobile software to use.

Both have advantages and disadvantages. It's hard to determine an absolute "better" in this case because it's all subjective in the end. 

How I wish Apple starts using Anroid.

Android is the best cause it's almost complete & open sourced OS but not as secure as IOS

Andriod, easy to use and lots of productive apps are available and free of cost.

Android is better to use. It more vibrant and you get more flexibility than iOS.

android is better than ios because it is easy to use and not complicated and as we see android mobile are use in over the world more than ios mobile

Android may be easier to those with just a simple knowledge of Java, however some may find iOS easier. Think about market share, and who has the most end-users. In my eyes, iOS would be your best/safest bet. However, this does incur more work.
