In addition to the prestige and career boost, you get a a really swell awesome feeling and get to be a permanent part of the encylopedia of knowledge. You're in libraries now!
In chemical physics, many of the most influential papers (tens of thousands of citations) have been published in The Journal of Chemical Physics, an absolutely non-flashy publication with impact factor ~3 and a myriad of uninteresting papers.
That happens if you publish in any indexed journals. Perhaps more people will see your name if you publish in a higher profile journal, but that is also not a certainly (though highly probable)..
