Pros
Pro One of the only ways to sell second hand game keys
If you have product keys for games that you don't need, you can sell them on Kinguin. It works similarly to Ebay, but it's a marketplace dedicated to keys.
Pro You build up a little credit per purchase
You get a few cents of credit per purchase you make, if you have a Kinguin account. That can make some difference after a bit.
Pro Usually doesn't get cheaper
Websites like Kinguin and G2A are usually the cheapest way to get game keys. There are tricks like using discount codes for -3%, -5% or even -7% discount. These keys can usually be easily found through a simple Google search or through a Twitch streamer who's partnered with Kinguin. Another trick is not to use the shield service. It's usually a waste of a dollar, given the fact that in reality issues with game keys are rare.
Pro Typically significantly less expensive than competing services
As G2A is a user marketplace, keys may be purchased during sales and resold for significantly less than current market value. Because of this, keys tend to be very inexpensive in comparison to Steam, Origin, and Uplay.

Cons
Con Sellers could possibly be shady
While keys are usually legitimate, there is often no way of telling how these keys were obtained. There are cases in the past where stolen credit card information was used to purchase a bunch of game keys and then those keys would be sold on platforms like this. So in that way it's similar to Ebay as well. However, it may be that it's blown somewhat out of proportion by gaming publishers who would earn more off gamers if they'd buy brand new keys.
Con Risk of stolen keys
As G2A is a user-driven market place, not all keys sold may be legitimate. Anyone from anywhere can list a key for sale à la eBay and Amazon. However, like eBay and Amazon, G2A provides the seller's feedback rating and number of sales prior to purchase.
Con Opt-out service on checkout that is easy to miss, which charges and subscribes the purchaser to something they may not need or want
Many people have reported issue with the "Shield" subscription service, that seems to auto subscribe users when purchasing keys. It has also been reported that is is pretty difficult to get this subscription turned off, which can be frustrating for those that never wanted it in the first place.
