With a correct design, bemf detection is as reliable as hall effect sensors commutation, I have designs running up to 70000 rpm's where the motor never stalled. sensorless is the way to go

Can anybody tell what is the diffrence between Hall effect sensor and BEMF control of BLDC in the chance of commutation failure?

I need to deceide which way to go.Sensorless would be better for cost consideration,but how about the relaibility ?
