You don't say whether you're asking for online or offline play, but if offline and/or mission building is your bag, go for it with the last official version.
As long as your pc is up to snuff, it's a great flight sim with flaws.
If it's online play you're after, stick with '46 for now. Most of the current CloD servers are running the last Beta patch, which has quite frankly ruined it for me for a variety of reasons, mainly getting a slideshow with any more than one on one combat and reduced graphics quality. Then there are the huge FM questions in the patch covered adequately elsewhere.
That said, I've just re-installed '46 for a look, and simply can't go back either I'm afraid.
