Endermen
Since Endermen is rather tall, I find the best way to kill them is standing in a two-block high space, and simply use a sword. I either create this roof above using dirt or similar, or stand under a tree in the vicinity which has leaves in that height. It's quite normal to see endermen during the day.

If you attack Endermen in The End, you could use the same trick, but another trick I see someone using is to place a water block right below your feet, and stand in that water when attacking the Endermen. (Also note the trick of wearing a Pumpkin to not aggravate them before you want to)

Creepers
Regarding creepers, I've found that the simple tactic of run-and-hit usually works rather well. Just run straight true them, whilst hitting them with your sword, and if they blow up, you've already passed, so no worries.

Another tactic could be to use bow and arrow, or run-hit-and-retreet. I don't like the latter, as I find it a little harder to get close enough for a hit before retreeting.
