S4 Downgrade topic

Hi everyone, I currently have a samsung galaxy S4 I9505 phone running android 4.3. I upgraded to 4.3 via Odin not via the inbuilt software update. Im wondering if it is at all possible to downgrade to 4.2.2 because with 4.3 their has been an introduction of a lot of bugs to apps such as Chrome and Spotify. These bugs have since been really getting annoying and the only time I didn't have to deal with them would be when I was running 4.2.2.

Alternatively can anyone tell me if upgrading to android Kitkat for S4 would potentially fix these problems?

Any help will of course be greatly appreciated and even if no help can be given thanks for taking the time to read this post.

Regards
