Sell or Lease Question - Leon County TX

I’ve been offered $2000 per NMA by one landman and another landman wants to lease my 4 acres for $175 per NMA, 20% royalties and 5 year lease. The NMAs are located in Leon County TX in the Copeland - 162 survey. I’ve done some research and received information from this site but things have changed a bit and it looks like both offers are very low. But I wanted to get real information from the expertise on this board.

Thank you all information is appreciated
