'Divots'? Well, a reel mower physically cannot 'scalp' like a rotary blade mower because the bed knife prevents the rotating blades from contacting the ground, but obviously the wheels can't fly over the dips. so there will be uneven cut heights. Will you notice it? Depends on the severity of the dips as well as the exact type of reel mower - whether it has more than two wheels, which can reduce the effect of following hills and dips. The power reel was the first powered mower and is still the best for premium lawns/greens maintained at 1 1/2" or less.
