Onboarding speed and platform stability with prop firms - current experiences?

Curious what others are seeing lately regarding the actual onboarding process itself with various prop firms. I've been running into some significant KYC/KYB delays, and then once approved, the platforms often feel a bit 'buggy' or prone to execution issues, especially around volatility. It makes me wonder if some firms are prioritizing rapid expansion over robust infrastructure and reliable broker connections. What are your recent experiences on platform stability and the speed of getting set up and trading? Are specific firms notably better or worse on this front in your recent memory?
