This is what I have, the pink dildo is 7 inches, and the blue dildo is 8, but 7 insertable. I definitely prefer the blue one, not necessarily because it's thicker, but because it's dual density. It's just more comfortable and feels better.
And I'm not sure what the size of the plug is, but i like metal ones. And I like the fleshlight, but I don't use it very often.
