I voted for "One version of a mould only". Except for a small handful (which I consider 'special circumstances'), I generally don't buy multiples of the exact same toy. Other than that all my doubles were gifts that people gave to me when I already had the toy, so I keep the spare sealed. I have quite a few variants of the same toy (e.g. US and AU Transmetal Optimus Primal, Armada and Micron Legend Hot Shot, Hasbro and Takara Transmetal Megatron, yellow and blue Binaltech Tracks, and of course, various original G1s and reissues) - and having those variants gives me the chance to display them in robot and alt modes.

But usually when I buy one version, I don't intend to buy another version. I sometimes buy variants later on because that variant appeals to me and at the time I bought the original the variant didn't exist. For example, when Binaltech Tracks first came out, it was the yellow version, so I got it. Then later on Takara went and released the blue version, which of course looks a lot nicer from a G1 POV, so I went and bought that. Likewise when Masterpiece Starscream first came out in Japan, it was "Greenscream" -- then much later on Hasbro went and released their version with G1 colours, so I bought that. Had I known that those more appealing variants were to come out later on, then I would have held off and waited for them. But alas I can't predict the future (cos if I did I'd retire and win Lotto for the rest of my life ).

I'll open them and display them, that way I can display one in robot mode and the other in alt mode. The only time I'll leave something sealed is if it's an exact duplicate - and I usually end up with duplicates because they were gifts.

e.g.: my 1984 Autobots shelf:

Dion, Wheeljack and Prowl are the only figures on that shelf which I don't have another version to display in alt mode, but with the exception of Mirage and Sunstreaker, the second versions of all of those toys aren't true multiples, they're variants (e.g. originals and reissues). e.g. I have original G1 yellow Bumblebee, red Bumblebee, Bumblejumper and the various reissues of Bumblebee (as well as Glyph and Spectre ). My second Mirage and Sunstreaker were given to me for free.
