Objectively speaking, I don't think you will find Form mentioned a lot in the top vst charts.
Selectively using some criteria which is not in itself authoritative really, you have only compounded the fallacious appeal to authority by argumentum ad populum; which you want to support your facile notion of its musicality or not. In itself such a tool only becomes musical in the hands of the musician using it. I mean I don't look to 'the top vst charts' for anything, and I have no idea what you're even supposed to be pointing to.
Why not just stick with 'it's not my thing' rather than try and make that more than it is.
I agree with you 100%.
Having said that, people tend to talk about things that they really like. So when something isn't talked about much, or at all, you do have to wonder how "good" it really is at what it does.
For example, I never talk about Revitar when people ask about VSTs for strumming guitar. I mean it's not God awful but compared to the quality stuff we have today, I can't see a reason for using it unless you want a sub standard performance. And I do have Revitar and did used to use it before I got things like Real Guitar and even VIR2 stuff. But since then, I might as well delete Revitar off my hard drive.
Form? I tried it out for a bit when I first got Komplete 11. I honestly don't remember what I thought of it because, quite honestly, I have way too much stuff. It's all starting to blend together except for the few things that either really stand out or, things that I have for a very long time and know inside out.
The things that I own that I use almost all the time?
Pianoteq 5 (almost exclusively for piano parts)
EWQL Orchestral Stuff (at least until I get VSL this month)
MODO Bass (the only bass I use for electric bass)
Real Guitar (The whole line)
VIR 2 Guitars (Electric and Acoustic)
For stuff like drums? Eh, nothing really stands out. I'll use Battery 4, samples, Kontakt factory stuff, whatever strikes my mood
For synth leads, pads, FX, etc., eh, again, it's all starting to mush together. And with over 100 of these things, there are days when I just look at the list and close up my DAW and go play a dungeon crawler. Truth is, because there are so many good synths, there are very few that I turn to all the time.
But I do know this much. There are a few things that I do own, like Revitar, which is free of course, that I know I will never, ever use again. Most of that stuff I have gotten rid of. Some still remains but will eventually be tossed or sold.
Point is, that Form is rarely talked about (if that is in fact the case, and I'm not 100% convinced it is) there has to be a reason. Because people do talk about the synths that they love.
At least that's been my experience.
