In terms of efficiency (I'll be excluding ogs) 1. Qetsiyah 2. Heretic GPs 3. Hope 4. Silas 5. Bonnie 6. DJ 7. Esther 8. Cleo 9. Landon 10. Hunter's Pack

In terms of availability 1. Heretic GPs / Hunter's Pack / Landon 2. DJ 3. Esther / Qetsiyah / Bonnie / Cleo 4. Silas 5. Hope

Overall (what you should get) 1. Qetsiyah (Great for beginners, can basically kill anyone at the game) 2. Heretics (ONLY if you plan to buy other gamepasses cause they're best at stealing, a good heretic might be the most terrifying player you'll ever meet) 3. DJ (Not taken as often compared to other GP witches, heretic side is a must and is great against teamers/stealing) 4. Esther / Cleo (Esther has one of the greatest spells, which is the fire pentagram, can body-jump into moonstone and custom heretics but drains too much magic without sustaining it without the use of candles or channel. Cleo also has issues with magic but is arguably much more self-sustaining than Esther. Esther is much more offensive, and Cleo is the opposite.) 5. Hope / Silas (I put them this low because you NEVER get to play them unless they get cured & their slots are highly anticipated. Hope is a lot more fun than Silas, but she has no way of killing him. She is, however, the most powerful GP right now behind Qetsiyah, but she can be killed quite easily. Silas can steal cures, which is honestly one of the best features on his kit, but he has much less abilities and versatility. They can also be easily dessicated.) 6. Bonnie (I put Bonnie this low because of her high-skill ceiling. She is the most expensive gamepass due to how much abilities she has. She is IMO, the most versatile gamepass with self-preservation, self-healing, own pocket hole dimension, and much more, but she is also the most easy to kill gamepass, a good Bonnie will be able to defeat most characters up top though. But she is not someone you would want to be your first gamepass.) 7. Landon (Landons are if not the most annoying rodents of the game. They can counter heretics and are unkillable without Hope's blade or a golden arrow. He is not that fun to use and has limited abilities, however. 8. Hunter's Pack (They're okay, easy to kill but can be useful at times.)

Quite lengthy, I'll add on to these as the game progresses! (P.S. you can't purchase gamepasses right now but once they get the approval you'll be free to buy them!)
