I believe this is why I see so many Buzz songs with about fifty effects in them, trying to make the Buzz generators sound better.
You're right in a way but wrong in the same time. Right because I think that adding zillions of Fx after a generator kills the sounds. As I wroted somewhere, any added Fx in a chain distorts/alter the original sound. That's why often the songs that use a lot of Fx sounds very
thin.
Wrong because a lot of gens sounds very good, are powerful and can provide a wide variety of sounds. But I agree, there is no magical preset because there is no Fx included in the gens. So that means that you have to tweak a lot. But, what is interesting, even if it needs a lot of work and learning/trying/testing, is that you can then create
your sound. The sound nobody else have. Artisticaly speaking this is very important I think.
I dont use a lot of Fx, I'm more concentrated on tweaking the synth/gen to get the sound I have in mind as near as possible. Then I use Fx. Mostly chorus/EQ/reverb. When you use these three Fx, you make your sound a lot more better. And after that you can add other Fx that will add
magic to the sound.
I have tons of VST (mostly free, about 350 free vst maybe even more) but I use a very few of it, mainly mda Piano and ePiano and the SampleTank freeware. Or some stuff like Alchemy (freeware version) or Independence free. But even these I tweak the presets

And I like a lot using soundfonts with Jeskola XS-1 which is
the best soundfont player around the world.
Did you try Qsamo ? This is a wonderful piece of synth, with killer sounding. And it's a gen

Same for GreenMilk, 6Ultra_L, etc...
But as you noticed yourself, every musician have its own way to create. It's a matter of taste. As a non-musician (I dont know music theory and I dont play any instruments) I like the act of creating my sounds myself, I dont like very much the "
just push a button" way. But it's my problem
