I've never used OT-1 T cells, but the B3Z system is very reliable, and
extremely sensitive (it can detect femtomolar concentrations of the
peptide).  Its sensitivity, ease of use (colorometric CPRG assay) and
speed of readout (usually visible in under 30 minutes from time of adding
reagent) made it the gold standard in the Shastri Lab.
