I've never owned a .270. Not because the Campfire told me it's ghey, but because of the weird diameter - .277...WTH, where'd they get that number? Japan maybe, or so I read somewhere.

I've also never had a 7 mag, and that is partly because of bias. By my observations, they're often fielded by the clueless. Kinda like my uncle's drunk buddy who showed up to deer camp back in the '70's with one of those big ol' Western W49 Bowies on his belt. Big hardware, no idea how to employ it or whether it's appropriate to the task.
