Anyone else finding KYC/onboarding a huge variable across prop firms?

Been looking at a few different prop firms lately, and the onboarding process, specifically the KYC hurdles, seems to vary wildly. Some are quick, almost instant, while others feel like pulling teeth, asking for multiple proofs of address and identity, sometimes in formats that are difficult to produce quickly. It makes me wonder if there's an underlying reason for the disparity, or if it's just a reflection of their internal compliance teams and chosen PSPs. Curious about others' experiences and if this affects your decision-making beyond the obvious capital and payout terms.
