Default ICS keyboard or Swiftkey 3 ?

After using Ino One( Non-camera Android phone ) for about a month, I am more or less accustom to Android OS. If not for my job which does not allow me to carry non-camera phone, I do not think I would want to use an Android phone. Simple thing such as using the keyboard is giving me the headache. Although it is said that keyboard has improved alot since gingerbread, but it is still no match for IOS. I get a lot more wrong words using the default Android keyboard than any IOS version. Of course there are better 3rd party keyboard around in the Google Play store but there is a concern for security. There might be a possibility that these keyboard apps might be collecting key stroke data, thus compromising passwords. Putting security concerns aside, I installed Swift keyboard 3. This app is great. I get more words correct using it but I get less battery juice, as it is running in the background even when I am not using the keyboard. I could not live with the shorter battery life, so it is back to the default Android keyboard for me. I seriously hope Android will improve more on the basic features such as the keyboard instead of giving new features I don't use on a daily basis.
