From a quick look at both planes it might be that going into deep stall in the 727 might be easier because the AOA needed is smaller, but that's just my quick guess

(For those who don't know, a Deep Stall happens when the horizontal stabilizer gets in the "air shadow" of the wings, hence you can't get airflow there to move the plane)
