What you're missing is that cubesats, as secondary payloads, generally can't
fly any energetic propellant. Water is so inert, however...
The butane and water resistojets are usually inert enough. Butane leaking
could potentially detonate, but pressure is so low the risk is trivial. Water
is best, and can electrolyze....

Website mentions 150-175 s Isp for water.
OTOH, 90 % H2O2 has a similar Isp at around 900 °C decomposition. What am I
missing?

You're not the only one considering electric water thrusters:
