Agree with cratz2. You somewhat have apples and oranges there to some degree.
Only reason I must comment without knowing more about your intended need or use is I just got An E2E recently. It is not my first SF, but I am pretty amazed and exceptionally happy with the E2. It is small, solid and bright.
If this is to be your first SF, I think the E2E is the best choice. Great size for EDC. The 9P is a little big for most people to pocket comfortably. Clickie tailcap which is my preference. The L1 and 9P are twisties.
The E series bodies are the basis for many interchangeable SF parts. For example if you shop around on eBay or B/S/T lights here on CPF, you can pick up a KL1 head for about $40. Gives you an E2E and an E2L.
No wrong choices on your list, just different.
