Can you name me a few bike brands that make stronger carbon frames than others? I've been reading and searching but found articles years old.

I'm trying to decide whether to purchase aluminum or carbon frame. I am new to road cycling and do not want to worry my bike tilting over and cracking but at the same time would like to own a light weight bike.

I'll be test riding a few bikes tomorrow and if you can please name a few so I can ask the LBS for them.

Thank you.
