Level 2 has helped me out quite a bit as a relatively new investor / trader. To me, Level 1 is like purchasing a used car and taking it for a test drive. A test drive may not reveal other hidden things that could be going on with the car. However, it may be enough for some car buyers who have a general knowledge of how cars work.
Level 2 is like taking it to a mechanic and having him point out additional things under the the hood of the car, so to speak. He may find something with the engine, cooling system, etc (MM games, dilution) which may influence your decision to purchase.
I would suggest, as Cintrix said, to try a trial. I am on a trial with InvestHub and may continue with it. I like what it shows and it helps me to make better decisions. However, if you are confident that your test drive (Level 1) is enough, there is no need to take it to a mechanic (Level 2).
