For instance, while Azur Lane may have no pity system outside of specific events, the rates are much, much better. A 5* in Genshin has a 0.6% rate (90 pity, and potentially a 50% chance as to whether or not you get the character you want) whereas in Azur Lane you have a 7% to pull from the Super Rare pool, with event characters having increased odds compared to non-event characters. Pulls are much easier to farm in Azur Lane, requiring a specific resource and the general currency and both can be easily farmed and stockpiled for later use (the specific resource in particular will become a non-issue after a few months of play). Genshin, on the other hand, drastically slows down the pace of wishes once the world has been explored and everything possible has been done. Without paying, basically one wish in a bit less than three days (60 primogems per day, wish is 160, not counting events or abyss which give around 3-4 wishes per run, so let's say around 22 wishes per month, with Welkin Moon bringing that up to around 39-40 wishes per month). In Azur Lane, it is not uncommon to farm 10 or more pulls per day at minimum.
Both games encourage pulling repeats of characters for improvements, but Azur has generic enhancement units that work for all characters of that tier that you can acquire in various methods (limited farming/weeklies/login). Genshin does not. You must brave the gacha for constellations/refinements; you have no other option.
Both gachas are going to mostly give you the equivalent of vendor trash, but only 30% of the pulls in Azur Lane have no value other than being used to enhance other characters. Everything else is either desirable or can be exchanged for other currencies for more desired characters/equipment/consumables. In Genshin, however, every 10 pull is going to likely result in 7-9 pieces of trash that can only be used to level equipment and at least one 4* weapon/character (but probably not more than three).
Due to how long it takes to build up wish stockpiles in Genshin, buying crystals is encouraged due to FOMO which is the least efficient monetization method on offer. Azur Lane gives the player plenty of pulls and trends towards people buying character cosmetics instead. But if you did buy more pulls anyways...11 or 22 pulls for $10 versus Genshin's 12 pulls for $30.
TL;DR - Genshin's wishes after a certain point aren't farmable outside of dailies/events/abyss/content updates. Azur Lane's wishes are always farmable and more likely to give you what you desire even with the much larger character pools. In Azur Lane, so long as you keep farming you will get what you want eventually. Genshin can eat up your entire wish stockpile and still fuck you over by going high pity twice and losing the 50:50 (this is how I almost missed Ayaka and didn't get Raiden the first time around) and you have no means to quickly farm more wishes outside of a credit card as it will take months to rebuild your stockpile.
Addendum - Azur Lane's premium currency is also farmable, to a degree.
