Well let me translate that a little better. Here's a rough outline:
Comparing T500 and G25 side by side reveals that the G25 now looks like a toy, both in terms of wheel and pedals.
The guy has tested G25 and Fanatec wheels, then went back to G25 which he preferred.
Button on T500 are all "micro switches" that allow for very nice and precise clicking. No jerkiness or such.
Shifter paddles needs getting used to since they don't move with the wheel. Compared to the G25 they feel massive and robust, clean precise shifting. Compared to this the shifting on the G25 feels wobbly and has no real pressure point.
About the FFB. Incredible. With the G25 you feel when you drive over a curb that the wheel tries to go into some random direction. The T500, on the other hand, just does it and in an extreme way. Great feeling.
When the car stands still, the T500 is confortably soft, but when the car exceeds 20km/h the resistance increases dramatically and you have to really hold on to it to turn. If the car starts drifiting at high speed this is unmistakenly felt by the driver. Trying to hold the wheel with one hand is futile, grab it or let go, otherwise it'll hurt (lol).
Pedals work clean, soft, precise without any sounds of drag/grind. The G25 seem to grind more, have some clearance and aren't as precise.
Connectors are on the back left and you don't need to detach the whole wheel to disconnect stuff.
Then he goes on how he was convinced about the G25 but he now prefers the T500 by a long shot and yadada. He mentions he played sims for 15 years. He's very happy.
One negative is when the fan starts up it is louder than the PS3 (not sure if he means just the startup or in general). But the T500 itself is quieter than the G25.
Then he adds, concerning precision, that drifting is child's play, you are flooded with with responses from the wheel, incredible.
