It's all about whatever floats your Cheerios, for sure.
But over the years, I've preferred the smaller screw-top jars. Specifically, the 8 ounce Ball/Mason canning jars. Mine are all the "standard" jars, but Ball does offer a squatter, wide-mouth jar, also 8 ounce, that, for someone just starting out jarring pipe tobacco, would probably work better -- those wide-mouth jars look better and they can be stacked; plus, it's easier to fill a bowl from them when opened.
I use the 8 ounce jars because, properly filled with tobacco, they hold about 3 ounces, depending on the blend and cut. Since I jar tobacco mostly to age it, it's worked out very well in the 8 ounce jars since I can open an aged jar of that size and it's contents is about the same amount of tobacco we get in a tin.
It's important to remember that, once you open a jar, the aging process stops. Which is no problem if you plan to smoke the contents up in a month or so, or if you don't care about continued aging, but if, like me, you like to ensure what you're not going to smoke right away is sealed away to age longer, that size jar is the way to go.
So ya, big-ass jars that hold 2-3 pounds are kewl, but not for me.
