The T2 does a few other things like program OEM calibrations, but only if you have a GM TIS subsription ($$$$)...
I believe it also displays some info in a supposedly more "nicely formatted" manner, for example it displays the misfire counters as bar-graphs.

I've dealt with both "authentic" and cheap Tech 2s. Mine is authentic with the original 1996 build date under the PCMCIA door, this date will not be there on the Chinese versions. I'm not suggesting you take the risk but I will say this. The knockoff I used did everything exactly like mine. They're still supported to those that say otherwise. They're updated VIA AC Delco Tech2Win which is a subscription based service that anyone can purchase. They're still pushing new updates monthly and support GM products from 92-current.
The CANdi module I own is ebay chinese. It looks and works exactly like any other I've ever used. My main cable also failed from being twisting around too many times. I picked up a chinese $50 replacement and the only thing different about it was the price tag. Keep in mind that since these things are shipping from China it might take a month for you to receive them and if they're damaged in shipping or they rip you off you're screwed. I took the gamble and got $700 worth of stuff for $150. Again, this is just my experience but I'm happy. Chances are, these are coming from the same place the real ones are manufactured.

So do I need a subscription to TIS to flash my BCM for the new 6L80e or flashing door modules for changes in mirrors? I dont care about flashing GM updates into the vehicle just want to be able to make changes to the BCM. I added an aftermarket camera that functions like the factory one and had the dealer flash my nav unit with a new VIN and it works great but now my damn backup sensors dont work and the DIC always says "parking assist off" or some crap like that. Its annoying because it chimes every damn time I put he truck in reverse. I just want to be able to change crap like that and to be able to do the ABS bleed procedure on vehicles I do brake jobs on.

Short answer You wont be flashing anything without a TIS subscription.
Lots of independent repair shops have the necessary tools as well.
