Updating from 9.0.2

[dfbhd13]

Hi, i am still on iOS 9.0.2 from when i first got my 6S. is it worth upgrading to the latest 9.3? are there any bugs \ problems in 9.3 that are a result of the upgrade that aren't in 9.0.2?
also after upgrading from 9 to 9.3 will my phone be wiped and have to be set up again, or is all the data carried over?
Thanks

Update 9.3.2 has a lot of bux fixes over 9.0.2 and also the performance is really good! Also using an iPhone 6s with 9.3.2.
AND nothing will be lost just in case make a iCloud backup or via iTunes.

DO NOT UPDATE if you wish to jailbreak your iPhone at this given moment.

Edit: Ok, that might have sound harsh. What I recommend you do, since you have that rare opportunity, is to try jailbreaking your iPhone and see how you like it. If you enjoy your jailbreak, stay on 9.0.2. If it doesn't float your boat, updating to 9.3.3 is a good idea.
