More natural in-room bass response is generally, but not exclusively, an advantage of sealed boxes.
According to Martin Collums and Dan Wiggins, "typical" room gain is ballpark +3 dB per octave below 100 Hz or so. Obviously this depends on a lot of specifics.
The 6 dB per octave rolloff of a low-Q sealed box works well in most rooms, but arguably a room-gain-complementary 3 dB per octave rolloff across the bass region would often work better.
A 3 dB per octave rolloff isn't practical for an unequalized sealed box. But a 3 dB per octave rolloff across most of the bass region (accelerating to 24 dB per octave below the tuning frequency) is feasible for a vented box design.
The devils are in the details.
