Tell me if I'm wrong, I only played 2e for a short time.
2e way is slower than 3e because you have to obtain information from the DM before you can determine if you suceeded.
In 2e...you rolled and got your attacks. The dm then told you the AC. You then checked your thaco to see if you hit.
In 3e....you roll and add up your number, and then just tell the dm what your attack is when your ready. The dm then determines if you hit based on the AC.
