Apogee vs Soundlab

Best I can recall, the big delta is that Soundlabs have much more energy from 100hz on down than any Apogee I've heard - including the big full range ribbon units and the "Slant" hybrid models. (I never heard the monsters with separate subwoofer cabinets.) On that basis, I'd prefer the S-L, although the fairer comparison may be to the Apogees I haven't heard. Disclaimer: there was a looooong gap between my auditioning Apogee and Soundlab so this is definitely FWIW.

If both speakers are connected with top notch electronics, definetely the Apogee.
More punch, more depth and realistic soundstage

I have always liked electrostatics, but worry about their dust collecting properties. So I choose Maggies, and they certainly come close to ES in sound.

I would say in terms of resolution they are about equal. Dynamics and sheer power, definetly the Apogee. Ultimate coherency the Soundlabs win. Both are top notch speakers.
