I had a chance to test
RGT FFB Pro and it was really great wheel - especially if you don't like the fact, that G25 has all buttons at the gearshift stick.
There are only two things where is G25 better (yes, I tested both):
1) Only sequential gs stick - can switch between seq and H at G25
2) Only 270 degrees turning angle (although I don't think that more is useful if you don't want to cruise) - G25 has 900 degrees
