Diva

This is the only plugin I ever bought JUST from hearing the init patch saw wave. I agree with everyone else, that Diva is the best analog emulation plugin to date. A must-have for electronic producers.

Since this plugin is praised so much, I will mostly be listing the cons. I honestly thought I would consider this plugin to be rated as 4/5 stars, but the sound is just too amazing and fat for such a rating.

Biggest problem with Diva, (not cpu!) is that it isn't really semi-modular. You can slap an LFO/EG to filter/FM/amp/tune/pwm, but most subtractive plugins already do that. You have a lot of ways to manipulating LFO's/Envelopes using the "add/multiply/etc" features, but doing so is FAR more tedious than modulation in most other VSTs such as Serum/Pigments/Massive/etc. The modulation is only really useful for engineering analog chaos. Real analog instruments may have the advantage of having infinite sample rate, but the real analog sound comes from the imperfections of circuits and how heat effects transistors. Diva has already engineered almost all of these analog features to the point that you don't need to reinvent the wheel. If you want to add some more analog chaos, then perhaps you can make use of some of the semi-modular features.

Additionally, you will find some knobs that you want to modulate, but you can't. The modulation is messy and very limited. U-he even made a separate tab for working with the modulators, but since modulation is so limited, I feel like it's just a waste of space/a tab.

Last issue is more personal, but I didn't find the effects very useful or good sounding. The only effects I liked were Chorus/Rotary. I'd suggest using external FX for reverb/ phaser/ delay.

CPU isn't much of a problem if you use high hardware buffer and a good soundcard. However, this plugin definitely uses the MOST CPU out of any plugin. If you do not have the hardware, then you must bounce everything to rendered samples, which is reasonably too much work for some people.

Now for why I love this plugin: The generators and filters are beautifully engineered to emulate the REAL analog circuits. There are 5 generators and filters that each sound like their own VST plugin. I'd almost consider Diva to be 5 fat sounding VST plugins in one, but without much useful modulation. I bought this purely for the sound, and many others will too.
