[CentOS] dm-crypt/LUKS the state of the art for block device encryption?

  it's been a while since i've played with filesystem encryption so,
on centos 5.4 (and other linux distros), is dm-crypt/LUKS considered
to be the state of the art WRT encryption?  i remember other solutions
like loop-aes and others, but what's considered the gold standard
these days?
