I'm a science teacher, and every time I introduced students to the periodic table I tried to use one of the extended versions. For people just learning atomic structure, that version is much nicer for building an understanding of the connection between atomic structure and the periodic table.
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.
Don't know if they still do it but about a decade ago there was a group in the DragonCon parade where each member would dress as a different element. Given it was DragonCon, I thought it would be funny if another group did the same but for imaginary elements and compounds like Flubber and Unobtanium. Comic books are full of that type of thing. Maybe a Periodic Table of Fantasy Elements could be made.
In Google, we have these things called peer bonuses. When you want to thank your fellow colleague for something nice they’ve done you can send them ~$200. Recently, I started a project where I wspend the peer bonus budget on luciteria.com/element-cubes. The grant approximately equals the average price of a lucite element cube. Soon™ I should have a full periodic table at my work desk!
This is better than most "periodic tables" in that the periodicity in it actually represents something real: there actually are (conveniently!) 18 infinite families of finite simple groups (corresponding to the 18 columns in a standard periodic table), some of which are related to one another in ways that somewhat justify putting them next to one another in a table like this; one family (the cyclic groups of prime order) really are different from all the others, to an extent comparable to how different the noble gases are from the other elements; etc.
