First off, about how many gems are we talking about?
If you will chose between Golem 1-->2 and Witch 1-->2 my choice would be the witch.
Because then you have got a new maxed troop, and the witch will become 25% better at the upgrade. A golem won't get much better at just one upgrade.
I've got TH9 maxed troops and I use gowipe a lot. 5 witches are 1750 DE, 2x golem = 1350. Makes 3100 per attack. = 6200 for just one clan war. Thus I use just 2 golems per attack, makes only 2700 DE for a clan war.
I hope this gives you more information about these troops. Good luck :)
