Someone on /m/ posted scans and asked for some translations. 4chan died just now so, here’s the Tau Drive vs Original GN Drive chart from p. 37:

Units Used In:
Tau: Thrones, GN-X, Alvatoore, Alvaaron
Real: Exia, Dynames, Kyrios, Virtue, 0 Gundam

Activity Limitations:
Tau: No TD Blanket is used. GN Particles are created through electricity, in other words, it’s an electricity to GN Particle converter. When it runs out of power it stops completely. Restarting and recharging require specific equipment and facilities. 
Real: TD Blanket is used. Basically, as a semi-perpetual engine, it never stops. But when the unit is not performing maneuvers, it goes into an idling status.

Color:
Tau: Red
Real: Green

Output Characteristics:
Tau: There isn’t a significant difference in output, but since the operation time is limited, in a drawn-out conflict the original GN Drives have a decided advantage.
Real: Again, there isn’t a significant output difference, but the advantages of unlimited supply and the ability to store particles come to mind. 

Detrimental Characteristics:
Tau: The highly compressed [particles] used in beam weapons are hazardous. They have an affect on the cells of living things, rendering regenerative medicine useless. 
Real: Basically harmless.

Development:
Tau: Since they don’t utilize TD blankets, they can be produced in a relatively short time. They can even be produced on Earth.
Real: An extremely long period of time is required to produce them. Additionally a high-gravity environment is needed for production.

Other:
Tau: With current technology, they can’t use Trans-am.
Real: Trans-am is built-in. With equipment only loaded in the original GN Drives, using highly compressed GN Particles, they can achieve 3x output.

I’ll do some more tomorrow. 

Oh yeah, here’s the artbook (just yoinked from /m/):
