I recently made an Amazon Star quilt (a Judy Niemeyer design) and the larger ruler was wonderful for sewing the final units together effortlessly.
I think these rulers are just like most other quilting/sewing notions. It is purely a matter of personal preference and I always suggest trying the notion first if possible before buying. I teach a number of classes, including beginners' classes and my first beginner's class involves no sewing machine. Students bring what rotary cutting supplies they own and learn those; or better yet, come and try the myriad of supplies I have and choose what they like best and then go an buy what they like. I once had two students who swapped cutters because they liked what the other had purchased. Everyone was happy! :-)
