Is it safe to update to iOS 5.1.1?

Question

Hi,
I have an iPad 2 (64GB WiFi) running 4.3.3 and an iPhone 4 (16GB) running 4.3.5 and would like to know if it is safe to update to iOS 5.1.1?
I've been doing some "Googling" and reading through this forum and what I found is not filling me with confidence... I know the much used "this is like a hospital and only sick people come here" answer, but boy there are lots of "sick people" around with iOS5 problems....
From my research I have found the following major problems:
Battery drain (will this ever go away???)
Problematic WiFi connections after update (worked fine before)
Safari crashes on sites with lots of pictures and video
Apps crashing more than they are actually working (all worked fine before update)
Unresponsiveness of device (as if it is not quite capable of running iOS5)
SIM card read errors (iPhone)
Bluetooth no longer connecting to factory fitted bluetooth car systems (iPhone)
My only previous update is experience is with a 3rd generation iPod Touch which after the update to iOS4 (which broke the video app) and then iOS5 (which at least fixed the video app) is only good for playing music. It so laggy that doing anything else with it is basically impossible.
The iPad 2 & iPhone 4 were designed for iOS4 and not iOS5. Are the iPad 2 & iPhone 4 processors up to the task of fully running iOS5 and specifically 5.1.1 without any glitches and lagging? I'd rather stay on the current version than having my user experience tanked by devices that it not quite capable of running the new version of iOS problem free. I am not one of those people that MUST have the latest version of iOS not matter what. My devices working reliably is much more imporatant that a flashy new iOS. I know Apple says that they are compatible, but they also said that iOS4 & iOS5 will run on a 3rd generation iPod Touch and it just does not....
Any comments and suggestions will be greatly appreciated.
Regards
Jamie

Talking about iOS 4 to iOS 5 in general, I don't see why not to update. iMessage, iCloud and all the new features. There is nothing wrong with 5.1.1 and no serious bugs. Most people's issues here are not related to the OS they are running. Then there are the habitual whiners who create accounts just to tell us that battery life is awful, but they do that after every update. After a week, they all disappear. So update. I can almost guarantee you won't have any issues, and you get all iOS 5 features. You won't regret it. <<=== Base on this justification, let me tell you what i have encountered with you guarantee.
After 2 week of upgrade from iOS 5.1.1, this is what I have encountered.
1) Replace my old SIM Card, as it was totally corrupted by iOS 5.1.1
2) 2 weeks after new SIM Card replacement, [No SIM Card Installed] error emerged. Eventually, you are required to reboot your devices everytime just to ensure your iPhone is back to normal.
If the above, is not an issue; please proceed with his guarantee and upgrade.
If one person complaint No SIM Card Installed issue, you can Blame on bad LUCK. Yet there are alot of people started to post about it; tell me it is their BAD LUCK as well?? There is some definate condition where cause this error.
GOOD LUCK on upgrading to iOS 5.1.1, You NEED it.
As of now, i am just praying when iOS 6 came out; i have not choice to consider upgrade.
