Not really true. MIG gives a false impresion of the quality of the welds you get for beginers. They look good but serious welders will tell you looks can be deceiving. Of the various types, each controls some feature for you and makes that aspect easier. MIG feeds the wire automatically, TIG allows you to have pure control over the arc, Stick is about a middle course you have arc and feed mixed together, but manual and dail control to some extent.
Remember this question isn't about MIG VS stick, which in the real world would be penetration Vs. productivity. It's about a flux core sub 300 bucks MIG vs a goodish most features stick. That's the deal here, stick is cheaper you just get more at this price point. You do need to be able to stop sucking your tumb welding wise.
