nad 3020 vs advent 300

hi folks, i'm a newbie w/ a cool uncle with some vintage gear. he'll ship me an old 3020 or an advent 300 if i do some research. i have a ar es 101 turntable and want to know if anyone could compare the phono stage of these two. the ar has a sumiko arm and ortofon cartridge. they will be drving some pretty efficient klipsch forte's. is one of these old timers dramatically better than the other?
