What the pricing really means
Prevail publishes their pricing upfront, which is a good sign. Assembly Neos requires you to contact sales for a quote. When a company hides pricing, it usually means the cost is high enough that they want a salesperson to justify it before you see the number. Always ask for total year-one cost, not just the monthly subscription.
