Android backup apps - Titanium vs Helium?

So, these two seem to be the two most well known backup apps, and I just wanted people's opinions on them. Especially since I will likely purchase the pro/full version of the one I decide to go with.

Is any particular one better if you don't have root?

What about if you do have root?

Any difference in the amount of content they can back up?

Is there anything any of them still can't backup if you have root? I am particularly interested in app settings/data (not the apks themselves, but the actual data the apps write). I assume backing up contacts, sms, and photos/videos are a given and I wouldn't even need to ask this.

Does any particular one have better features in term of storing your backup on the cloud/google drive?

What about if you need to restore the backup to a different phone?

Any other suggestions or comments about these two? Or even other backup apps?

Helium not connecting to PC after rooting phone

I backed up all my app data using Helium app before rooting my phone. Now after (systemless)rooting my moto g4 plus when I tried to connect helium app to PC it refused to connect.
I used chrome app for helium on PC.
Did anybody face this problem?
How can I restore my app data?

Helium Premium on Shield TV?

I bought Helium Premium for backups to Google Drive from my Shield Tablet and it worked great.

But I just got a Shield TV and while the "standard" version is available for download. The Premium version is not. I also tried to "restore license" through the same email on my Google Play account and it doesn't recognize it.

This is really annoying because I'd like to be able to play all of my controller supported games on my new Shield TV but cannot transfer any of my game saves.

Anyone know if it's possible to get Helium Premium to work on it? I contacted the dev a few days ago but have not received a response. So I'm at a standstill.

I also do not want to root so that eliminates other methods.

Helium - App Sync and Backup for non Root Users is updated (July 4, 2016)

For those who are not familiar with Helium backup:
Helium is the missing app sync and backup solution for Android.
Helium does NOT require root. All Android users can use Helium to backup and sync Android applications.
Helium lets you backup your apps and data to your SD card or cloud storage. With Helium, you can sync app data from your other Android devices-- even if they are not on the same network. Set up backup schedules with Helium, and never lose data again.
Updated to version 1.1.4.2. Check it out https://play.google.com/store/apps/d...ikdutta.backup

Problem with Helium Backup

Hi,
I wanted to make a Backup with Helium Backup before unlocking the bootloader.
I set it all up but when I start a Backup it asks for a password and then, after a while, fails with an error message and redirects me to the Desktop Backup Password in the developer settings.
I have a blank password set but it still won't do the Backup.
Did someone have a similar problem?

Greetings
