Let's exchange opinions on a strategic issue...
What is your approach toward mercenaries as Carthage or anyone else with a wide choice?
Since you can not use the decision so often, you have to choose. Choosing involves comparing profiles of the different units you can get... Gallic, Italic, Greek, Iberian, Numidian...? Which one(s) do you hire, and why?
I have just started the long 1st Punic War as Carthage, and so far my choice goes for Italic mercs, with the thought that quasi-Romans are the best bet to fight Romans... Future will tell me if that is reasonable.
