Is it still the case that the Monodevelop in 4.2.2 is the one to use?

I was reading that the Monodevelop in 4.3 and above was “not as good” as the one in 4.2.2. Is this still the case?

Should I install 4.2.2, keep the Monodevelop application from that version and then install the latest Unity3D? I am asking for both Windows and Mac versions (if there is any differences between the two and their Monodevelop installs).

Use whatever one works for you. If you have read somewhere that 4.2.2 is “better” than 4.3.x, and you believe it, then use 4.2.2. To the best of my knowledge no-one does this.
