Why the 4EAT is better then the 5MT
I am sure you al may find this article interesting, unless you have already read it. This is from 'hunter001' over NASIOC explaining why the 4EAT is better then the 5MT. This guy isn't talking out his ass either. Its quite long, but full of useful info.

All of us are forgetting the main advantage of the Auto-WRX: the AWD system itself. When we talk of "Rally Proven", the "proof" is actually missing in the Manual-WRX. Here is the reason why:
The VTD-AWD system of the Auto-WRX is the most advanced AWD system of Subaru, with a true torsen (torque sensing) planetary gear center differential, which works in association with electronically controlled continuously variable multi-plate clutch-packs. The torque split is at 45/55, with a slight rear bias in power, in normal driving, unless more is needed front or back. This system equals in sophistication and effectiveness, the best AWD systems currently available in the market including the Audi Quattro (not the "Quattro" present in the Audi TT, which is inferior to the VTD-AWD). The VTD-AWD system is conceptually identical to the AWD system present in the World Rally Conquering Subarus, the significant difference being that the WRC cars have driver adjustable torque splits and are much more of a heavy duty kind. The hardware otherwise is identical in design. The Rally Subarus also have a true auto-manual transmission, which is actually a clutch-less manual, but the underlying AWD system is better adaptable to the Auto-WRX, not the manual-WRX, due to which the manual-WRX soldiers on with an AWD system that is essentially tractor-technology. "Gets the job done" but nothing to write home about.
The other Auto-Subarus do not have the torque-sensing center differential and drive more like a FWD car in normal driving.
The manual WRX on the other hand, has the same Viscous coupling AWD system present in all other manual Subarus, which is a reactive system, as opposed to the proactive nature of the VTD-AWD system of the Auto-WRX. The viscous fluid which is used to transfer torque front/back needs slippage before it can react and transfer torque. Also, since differential lock is acheived due to the viscous fluid being twisted (unlike the torque sensing incredibly sturdy planetary gear differential in the Auto-WRX), the torque-transfer is both slow and in-efficient. The AWD system of the manual WRX cannot be compared with the Audi Quattro or any other sophisticated AWD system. It does not have the breadth of operation (cannot transfer the amount of torque front/back like the VTD-AWD), the reactiveness (reacts slowly due to its very Viscous coupling nature) or the rapid torque transfer characteristics (due to the "reactive" nature of the system) of the VTD-AWD equipped Auto-WRX. With the Viscous coupling AWD system present in the manual-WRX, Subaru certainly would not be winning many rallys....just a heads-up.
Everything else remaining the same, I would have preferred a manual in the WRX. But in this particular case, everything else is not the same. Far, far from it. Let us face it - we admire these cars for their AWD systems and not for their "manual gear shift capability". So on that criteria, the Manual-WRX has a huge and glaring deficit. just my 2c
Later...AH
