solid wire or flux core

[sparkey]

Just would like to get input on weather to us solid wire or flux core. Which is cheaper or better to use? Does the flux core have problems like stick after sitting around for a whileand gets damp? I'm looking at buying a miller 210 for the farm. What are the quality differences between the miller, hobart and lincoln? I want to do it right the first time instead of purchasing and then regret it latter. I like this message board for ideas and the projects.
