I have JB's Evil Drums in both the BFD and SDX versions and I prefer the sound of BFD...
I've been a long time user of Toontrack Superior since back in the stone age with the DFHS version and it's great,but these days I much prefer using BFD2...
I still use S2.0 and many of the SDX's because they sit well in pop productions,but the sound compared to BFD is a little compressed and not as dynamic to my ears...
I have most of the expansions for BFD2,but even the stock library is comprehensive and really useful...
I can highly recommend BFD2 to anyone out there wanting great sounding drums in their tracks, but as has been stated here and on other forums,I would suggest getting the 24 bit files because they do sound different than the new 20 bit "diluted drums" :)
And let's not get into another argument about 24 bit v 20 bit files please ! Thanks
