I have zero experience with a Tig so I can't comment on that.
Personally I think stick gets a bad rap because some people think it's outdated but sometimes the old way really is better. Now having said that don't undersell the MIG either, that truck frame can be welded just fine with MIG if the right wire is used. Even standard ER70s wire can equal 7018 and some of the duel shield wires are light years ahead of any of the 70,000 tensile stick rods, there are a number of MIG wires out there that will produce a weld superior to 7018 and in fact there are wires that will meet or exceed most of the stick alloys. Which process is chosen for a certain job depends on a great many factors but given favorable circumstances in each case MIG and Stick will both yield equal welds with MIG usually being much faster, when talking about MIG wire you simply can not compare the common mild steel solid wires with the alloy duel shield wires.
