In general, you should check the weaknesses of the monster you want to kill! For example, if you have a Slayer task, what are the weaknesses of the assigned monster. Then, choose your weapon according to that.
If you compare stats (which you can do easily in runescape.wikia.com), the longsword seems to have better stats in general, especially for stab attacks; but if your monster is weak against slash or crush, I guess the scimitar is better, because of its higher speed.
The scimitar has a higher DPS than the longsword.
