I’m more interested in the age differences between the people choosing A314 or IG..
A lot depends on your age, personality and that of the people around you. I’d say IG is the more youthful, smart/dashing status and you know how younger women warm to a smart and dashing young man! 
A314 is the more complete, mature, in-control and in-charge status. Wich is also good of course.
Even at my age, I find IG can be very useful if I’m around younger people and I’m not wanting to overly emphasise the age/maturity/status aspect.
IG is a great base for a pleasant/smart/sociable status mix around girls in their teens/early-mid twenties IME. Once they get past their mid twenties, they do start to lean towards more overt/mature sexual and status/sexual mixes and by the time they are into their thirties and above, then most will tend towards the mature status of A314 - but you still get the odd exception. Also IG is a good one around younger Asian women, who can show quite an affinity for Rone.
TBH, I’d suggest you try both and see what does best for you in a range of situations. Remember AD’s warranty is excellent, so if IG doesn’t work out for you, you can always get the money back against something else. 
It seems like everybody refers to IG as a weak A314 is that the case? If so would IH work with it as well as it does for A314?
No, its not a weak A314 - IG is a very different product with different status effects - simpler and more direct, yes but well steered to be bright and sociable.
PrettyRickyBoi - You mentioned you come across as more intimidating sometimes to others without pheromones, and are also black which if in shape and masculine as I assume may then have a higher baseline testosterone leading to that. IG would be a great product for you as it contains no enone and likely would then work better with that base signature without needing to use steering addons like IS/IH/IG as you need to with A314 to tone it down. Its a charming, charismatic and warmer vibe, making you appear older and reliable (or also younger and more youthful if older), and certainly more approachable and friendly at the same time which is what you need… Its better for the social and dating side… One of the leading ladies here said it comes across like classic James Bond. People occasionally find a middle ground, such as adding P75 1.25-2.5mcg to add some of the dominant alpha back in (and at those doses much cheaper), or ammo/tuth/androstenone 2.5mcg per spray if they are older or need to boost their enone as well…
Solo the signature of the higher erone without enone attracts asians like a magnet, and with some enone in your base sig or added attracts latinos…
For those that are shy, dont maintain good eye contact or can come across as a take charge alpha, this signature should be easier to work with…
Heres a good older thread where several others discussed this as well:
