To develop smart contracts:
A) it's good to start with a local in-memory blockchain with unit tests but then deploy to the mainnet as rapidly as possible.
B) it's good to start with a local in-memory blockchain with unit-tests. Then, in the next step, debug and test the smart contract on a test-net like Ropsten or Rinkeby with beta customers to iron out last issues before deploying it to the main-net.
C) it's good to start with a test-net with beta-customers like on the Rinkeby or Ropsten testnet, before testing it locally on an in-memory blockchain simulation such as Ganache. Then deploy it to the main-net.

Starting with a local in-memory blockchain allows for initial testing and debugging. Moving to a test-net like Ropsten or Rinkeby helps identify issues in a more realistic environment before deploying to the main-net.
