I see the EZ and Equalizer line as specialized pistols for people with hand/grip strength issues who can benefit from the easy racking feature. If someone falls into that category, I'd go for one of them (likely the Equalizer, if they can deal with 9mm recoil.)

For someone who doesn't need the easy rack feature, I'd go with either the Shield Plus of and M&P 2.0 of some variety.
