The 10 frame boxes are a little more common and hold more honey, but a fully-laden a 10 frame honey super is a heavy thing to lift! The 8 frame Langstroth box is effective, too, but is a little less weight to lift. That said, when full with honey you are still enjoying a major bounty!

In summary, at the light/small end you can go with medium boxes with 8 frames and at the heavy/large end you can use deep boxes with 10 frames. And you can choose anything in between (deeps with 8 frames, for example). It’s really down to personal preference.
