Just my opinion...
May I suggest that you don't buy a new one. I bought a 12" Griswold a few years ago at an antique store for $70. Based on it's markings it was made between 1939 and 1957 (the year I was born). It needed a bit of work but it is the bomb. The surface is incredibly smooth, which is not the case with newer cast iron pans.
I've been told you can buy a new Lodge, and 'grind' it down (see You Tube) and that may be fine as well.
Bottom line, I think the larger diameter will suit your needs better. And of course, as I said earlier, this is all my opinion.
I bought a new Lodge 10" and 12" a couple months ago, and washed each with soap and water when I got home, dried them, then oiled them up and tossed them in the oven. The 2nd cook I did with the 10" was frying eggs, and even with the rough surface, they didn't stick. I also cooked a deep dish pizza in the 10" and it slid right out of the pan onto the cutting board when it was finished.
One thing you have to remember about grinding down and getting a super smooth surface is there has to be something for the seasoning to stick to. If it's too smooth, it will flake off. You need some texture for it to stick to. Most likely, the older pans with smooth surfaces are just well seasoned.
