I never really felt the need to get a proper reverb (beside the daw-included ones), but testing v-room changed my mind. It immediately filled my music/mixes with room (hence the name). It's sounding natural and full, but still clear without making the mix muddy (that goes for all 9 reverb-modes without an exception).
Another important part is it's easy to use gui. Especially for a reverb-beginner like me it's clearly structured and has a helpful tooltip while the cursor crosses a knob/fader. Some may say the gui is to simple, but i really like the simplicity without any embellishment.
There are many presets included that can serve as a good start, but it's in the nature of reverbs, that it's used best with own adjustment, depending on music and the desired effect.
I must admit, that i'm not really an enthusiastic reverb-tester and my initial test of v-room was mostly based on the good reviews that it got in several forums, blogs etc. but i can't imagine there's much better value for money concerning reverb.
And regarding the fact that it got several new reverb-modes during it's development from 1.0.0. to 1.0.9. it seems also like a good investment in the future, as i'm sure there will be many more modes in future updates.
