We don't use Smart Pricing (it's not very smart). I'm not surprised it prices your listing at your minimum price. I suggest Hosts use Dynamic Pricing (like PriceLabs) attached to their account. It is very affordable ($20/listing per month last i checked) and very accurate and well...dynamic; unlike Smart Pricing which is an Airbnb product that tends to underprice your listing.
If you want to choose between Smart Pricing and Price Tips...I might try Price Tips for now and see how it goes. The better option is using a Dynamic Pricing software.
