Gas lens uses a very fine screen etc to smooth out the flow.... and then - of course - none of your current cups will fit it. Typically also the SHAPE of the cups are different.
A couple advantages are smoother gas flow -- and less flow so less wasted gas. Not very important for a home shop - but a shop that welds all day every day will save some money on gas.... as well as they just flat work better.
BUT --- always a big BUTT in there -- it's like golf... if ya can't hit the ball - new clubs aren't suddenly going to have you shooting par.
