Is it actually harder to sell a 500$/mo B2B product VS a 1000$+/mo service? I will not promote

I once received advice that selling a 500-1k $ per month B2B product (even if proven with demand and PMF) harder than selling a 1000$+ per month service And to this day I’m not sure if that’s true or false because I keep cycling between either turning what we do into a product or a service (it’s in B2B sales and lead generation, which could be a product at that price, or a service) Would love to hear your advice if you understand both models and which makes the most sense and if that advice is true or false
