H1 serrated is supposed to have greater edge retention than H1 plain edge. Sal has said elsewhere that the edge retention of H1 plain edge is not quite as good as VG10 in this regard, which is "hard enough" for most purposes and easily resharpened.
LC200N plain edge is suppose to have greater edge retention than H1 plain edge. So. LC200N serrated "should" also have better edge retention than H1 serrated and, in turn, LC200N serrated should have better edge retention than LC200N plain edge.
H1 should be marginally better than LC200N in corrosion resistance (10 vs 9) and toughness (7 vs 5). So, the main advantage of LC200N over H1 is apparently in edge retention and, of course, H1 is easier to sharpen than LC200N (8 vs 6) but neither should be very difficult to sharpen.
See:
BHQ - Knive Steel Comparison Charts to see their comparative charts for LC200N and H1.
On the other hand, MagnaCut should have better edge retention than both H1 & LC200N, should be more difficult to sharpen and should be about equal in corrosion resistance to both. .I don't think I've seen a serrated Magnacut yet but the pending Native 5 Salt is supposed to be availabe in both plain edge and serrated.
The also pending UK Penknife Salt is also supposed to be released using LC200N in both plain edge and serrated. So, a direct comparison between Magnacut and LC200N in both plain edge and serrated in knives about the same size should be possible sometime in the (near?) future.

So, all other things being equal, it seems that MagnaCut (in either plain edge or serrated) would be best for heavy use, LC200N better for moderate use and H1 sufficient for light use.
