Should I get the smaller ignition coil?

I currently have a bigger ignition coil: Advance Auto Parts - Down for Maintenance
I’ve seen most people with the smaller ones, like this: https://shop.advanceautoparts.com/p...1-P?navigationPath=L1*14923|L2*15034|L3*16064
Which do you guys think is better? It’s going on a 76 Plymouth Duster with a 340 and 4 barrel 750 CFM carb.
