No experience with Lincoln, but I used a Hobart 140 for quite a few years. I changed to a Miller 211 more recently and sold the Hobart to a buddy. I have an argon tank (mostly for the TIG), but I have always used both MIGs with flux-core. I like being able to switch it on, weld up a small bracket, or do a big job, then shut it down without dealing with the gas. I do use the argon with a spoolgun for aluminum.
There is a bit more spatter cleanup, but anti-spatter spray can help with that if the job requires it.
