Attack Throws: What's More Clear?

Thanks for the feedback and analysis! 

 

# 1 is the most clear and is easier to understand.

I had to read # 2 three times to understand it, although I use exacty this method in my ACKS games - first I add target's AC to attacker's attack throw value, then I roll, and then I compare. It means the order of sentences should be swapped for it to be clear. (higher target number is more intuitive for me than 'armor as a penalty to roll')
