Acquired a nice 270 rifle at a good price. Want to mess about with something strange.

I was able to purchase 30 Gibbs brass from Quality. Very satisfied.I have a .270 AI and .30 Gibbs. This boils down to personal preference and how much extra work you are willing and able to do.
The advantage of .270 AI over Gibbs is that you can shoot factory .270 Win ammo. You cannot safely shoot factory .270 Win ammo or .270 AI because the shoulder is designed a lot shorter.
For my .270 AI, I do not fire-form, instead, I have an accuracy load for .270 Win (2919 FPS) and .270 AI (2993 FPS).
For the .270 Gibbs, you'll need to establish a false shoulder and do the cow method or have a custom hydraulic forming die made for it (i.e., from Whidden). Factory .270 Gibbs is available from x and https://www.rccbrass.com/product/270-gibbs/ but they are ridiculously expensive.
Below is a just a visual illustration on my .30 Gibbs.

From L-R ...
1. .35 Whelen virgin brass
2. After .30 Gibbs sizing die
3. After COW fire-forming method
4. After regular load fire-forming
5. .30-06 virgin brass
BTW, since Gibbs' cartridges book is scarce or non-existent, I purchased a CD version in Amazon ...

Prepare yourself to get inundated with a variety of opinions. I originally wanted to do .280 AI but everybody in their brother has one so I went with the .270 AI and very please with it. There is only a handful of us .270 AI owners here and a .270 Gibbs will even be going to be shorter ... and I am OK with it. Good luck!

Yep! I've bought 240 Gibbs, 6.5 Gibbs, and several AI calibers from Quality. All have served me well, and it's nice to have the specific head stamp when I'm reloading.
