Sandisk SD card confusion

Ok so I have several Sandisk memory cards that I use in my DSLRs, Camcorders, etc. I never use anything below class 6 and if I can I almost certainly use class 10's. One thing I don't understand is the difference between their designations: "Extreme", "Ultra", and "Extreme Pro". Now I know the Extreme Pro's are for ultra high bit rate applications, it can handle 95MB/s, but with the Ultra vs Extreme, I don't understand the difference. The bit rates of an Extreme and an Ultra often over lap...I took a picture of some of the Sandisk SD cards I use daily but these aren't all of them. I have another 16GB ultra laying around plus another 16GB Extreme (I work with video pretty heavily and often have to use my own cards with other peoples equipment).

Lastly is the symbol with the 1 inside the U meaning its UHS-1? Just making sure, I ordered a Canon EOS 6D recently [taking a bit to get here >] and I want to make sure using All-I compression over the inferior IPB compression is a cake walk....I checked Sandisk's website and they did have some comparisons but it wasn't very well explained, well at least in my mind. If someone could clear this up for me I'd really appreciate it! Thanks!

Side note: I noticed my Canon 550D sort of runs out of buffer fast with my Extreme Pro even though its rated for 95MB/s...in magic lantern I can't go past 1.3x bit rate while I can go to 1.5x with my Ultra's...no big deal I guess..
