The "long format (32-column) periodic table" is the one that makes the most sense to me. The ones that put the alkalis (and hydrogen) over on the right don't make sense to me, and putting helium in the same column as beryllium etc. sort of makes sense from the standpoint of electron shells, but completely obscures the chemical properties.
