Cryptgraphically the best know attack against truefish is as far as I 
know still 


I'm also not aware of any implementation problems on "some architectures". The 
only think I can argue against twofish is, that there are not so many  
cryptographical analysisis against it as agains Rijndael.

Can  you bring any paper, article or other resource that supports your claim?
