Followliker is cheaper,
but massplanner is more expensive in the long run and has a monthly or bi-yearly membership.
Massplanner has better quality, options, customer service, and tutorial modules
Followliker is a good budget solution for running a lot of accounts for cpa and such,
Massplanner is better if you are trying to run quality accounts.
For now I have low quality accounts, but I'm looking to change that in the near future to high quality ones. Sounds like I need to use Followliker now, but later on Massplanner then
