Actually, the OSes are not carrier branded. So long as you delete the Vendor.xml file, you can load the Bell .122 OS on your Telus Storm with absolutely no problem (I know as I've done this). The problem is that because the OS is not officially supported by Telus, if you install it on a Telus phone, they may make you revert back to the official release before giving warranty service and support.
Where the difference does come though is that each carrier has different testing requriements - because a lot of Telus customers are actually business clients, they need to be certain that the OS is going to work with BES systems as well as BIS, plus they need to ensure that it works with various carrier specific apps (e.g. Telus Radio, Telus Mobile TV, etc). They also need to ensure that the OS will work smoothly with the network (of course, because Telus and Bell share networks, this isn't as big a deal).

To be honest, I don't actually have an Telus specific apps, but from what others are saying, they don't have any issues.
But here's a great little post from over on the BlackBerryForums that explains what the vendor.xml file looks like:
Amongst other logical purposes for disallowing unwitting users from loading 'non-supported' software releases from other carriers, it can also be referenced to look at what newer versions of the OS are out there, as well. Sometimes, such as the case with a lot of the 8100 releases, there has been an 'empty' Vendor.xml file, which would need to be deleted by everyone in order to load the OS (rather than just someone from one carrier trying to load a release from another carrier).

I haven't notice much else that needs improvements. With typing accuracies, once you got use to the sure type or qwerty, it works fine. With 122, they have added a third option.
GPS and Google Map works great! Plenty good enough for me which is not good for Garmin as I was thinking of shelling out about $70 bucks for the Garmin GPS app.
Great little summary. It's also faster than .75 - both the camera and the browser are significantly improved
. I also love the full portrait keyboard. Works just perfectly if you've got small fingers 
. Other improvements include memory - I went from the 30-35MB range to close to 50MB with .122 (leaves more room for apps), although I've still noticed a memory leak - I'm not sure why though as others have actually stated very positive results with nearly no memory leak on their phones.
