Write a paper that you're proud of and that your target audience will be eager to read. (This requires knowing what your target audience cares about.)
There are roughly three classes of journals:
Elite journals. These are the rare venues that make people stand up and take notice. There's roughly one in every major field, but remember that a journal that is elite for one field may be considered marginal by others. For example, the rare computer science papers in Science and Nature are usually crap (cough D-Wave cough). If such a category even exists in computer science, it essentially means JACM and nothing else (except in graphics, where it means SIGGRAPH and nothing else).
Good journals. As a good rule of thumb, these are the journals that the top people in your target audience publishes in, and that publish the papers that the top people in your field actually cite. Again, which journals are "good" depends on your field. I suppose this is what "JCR" is a proxy for.
Write-only journals. Thousands of pages, costing thousands of dollars, that almost nobody reads or cites.
Finer distinctions between these categories are pointless. Other metrics like the number of issues/articles per year, are utterly irrelevant. A long time to publication is frustrating, but also ultimately irrelevant; this is only an issue of latency, not throughput. Assume it will take a year and plan accordingly. Meanwhile, you're already published your results in a good conference, right? And you've put a full version of your paper on the web, right?
Ultimately, your work is not going to be judged on the venue in which it's published, but rather on the impact it has on the research community. There are crap papers in JACM, and there are groundbreaking papers in write-only journals.
So where should you aim your paper? Be respectful but brutally honest with yourself. If you really have a once-in-a-lifetime breakthrough result, send it to an elite journal. If you have a good paper that will be interesting to a large segment of some intellectual community, send it to a good journal. If you have some decent results that could be published somewhere but only a handful of people would care about, I suppose you could send it to a write-only journal, but why bother?
In other words, stop worrying about how to play the game and just do good science.
