If you're primarily chasing sensitivity, one can generally be much more sensitive with a non-platinum thermistor. They're less stable but exhibit a much greater change in resistance with temperature.
A good voltage reference (or current source) is important, but even more important is building up a reliable bridge topology.

I think I had other problems like controlling amount of power dissipated on the sensor (large changes in resistance mean large changes in amount of power dissipated) and possibly other.
