Genshin Impact 3.6 will release 4 banners of Nahida, Nilou, Baizhu, and Ganyu. It's hard for F2P players to select only one banner to invest in. Let's see some recommendations before making the decision here.

Table of Contents

#1. Nahida

Nahida is the safest option because her power has been demonstrated. She was designed to create Dendro Cores for her team. The Dendron archon is helpful for both single-target and multiple-target teams.

That's why she is always one of the top-picked characters in many domains and Spiral Abyss challenges. Nahida is the best option for F2P players in the upcoming update.
Nahida is the most worth-investing Dendro character in Genshin Impact now. 

#2. Baizhu

Baizhu can make good some shortcomings of Nahida's kit. He gives DMG buffs to many Dendro-based teams, such as Bloom, Hyperbloom, Bur­geon, Spread, Quicken, etc. But he needs another Dendro supporter in his team to provide a subsidiary Dendro aura.

According to many gameplay videos, Baizhu is not a good off-field Dendro applicator. But he is still a good option in the next update if you have got Nahida. The pharmacist from Liyue has a healing ability, which is better than Nahida.
Baizhu is an interesting option that you should roll if you have had Nahida. 

#3. Nilou

Nilou is a strong Hydro character. She is also a top-pick character for Spiral Abyss, but Nilou's teams are often used for multi-target challenges. The gorgeous dancer from Sumeru often supports Nahida in Hyperbloom, Bloom, and Bur­geon teams.

However, Nilou is not very flexible. She is only useful for Dendro and Hydro teams. In addition, it's pretty costly to build a strong Nilou. You need to give the signature weapon and unlock high constellations for Nilou to make her strong. Therefore, she is not a good option for F2P teams.

You may want to get Nilou for Hydro and Dendro-based teams. 

#4. Ganyu

Ganyu has been rerun several times. Moreover, the pick rate of this character is decreasing. Many mobile players do not like the aiming-shot gameplay of this character. Therefore, she this the least recommended character in the next update. She was even picked as one of the top regret-pulling units in this game.

In conclusion, Nahida is the best character to roll in the next update. Baizhu is the second option for those who have got the Dendro Archon. If you have spare Primogems, you can invest in Nilou and Ganyu's banners.

Ganyu is still powerful but she is less used due to the change in the game meta. 

Bonus: Skip Update 3.6?

Four banners in update 3.6 are attractive though it's hard for you to select. However, you shouldn't skip this update. It's a great chance to get two powerful Dendro buffers for many meta teams now. They can trigger many elemental reactions.

Moreover, Nahida C2 is highly estimated. Therefore, you may not want to miss this opportunity for Nahida C2. Baizhu is also a great option for a Dendro healer and buffer. You can use this Dendro buffer for strong DPS, such as Raiden Shogun and Ayato.

Don't skip Genshin 3.6 banners.
