I have owned both. The T8 has a faster, lighter sound, while the S-30 has more weight, a fuller sound. I was using them to drive my Merlin VSM-M. Both worked well but I'd give the nod to the S-30 (despite its weird looking shape, it is long and does not fit well on a rack or stand). In the end, I sold the S-30 to pick up a pair of Atma M-60 MkII and could not be happier. Also, consider using the Zero autoformers to increase the speaker impedance to make it an easier load for the amps.
