I suggest you visit wikipedia. These pages list the complete armament capabilities for both aircrafts and you can click on each weapon system to find more information about it:
https://en.wikipedia.org/wiki/Fairchild_Republic_A-10_Thunderbolt_II
https://en.wikipedia.org/wiki/Boeing_AH-64_Apache
A-10C, AH-64D and UH-1H are completely different modules - you won't be bored.
Mavericks and Hellfires are both Air-To-Ground missiles, but they work completely different - at least most variants. The laser guided Mavericks and Hellfires share some similarities, but otherwise it is a fire & forget, optoelectronic missile vs a laser guided missile (or radar guided, when the Apache gets the Fire Control Radar upgrade).
