Grandma was a firm believer in rolled biscuits, auntie only made drop biscuits, which made grandma mutter under her breath. All of it was so long ago that I really don't remember the difference but I know I liked both.
Rolled are flakier, and easier to split. So, if you like butter, preserves or other spreads on your biscuits, rolled rule. But, if like me, you eat the tender quick breads "au naturel", then drop are easier. I also like both.
