I'm not a big fan of Waves , but for sure , they have a top notch support ...and ususally plugins are ok from day one .... it's one of the "solid" recommandation i make to my students .
The best bang for the buck i found is the Gold , you have a great price and tools ...
i find a lot of brands gravitate around the same stuff ...but when i need a stereo imager , denoiser ,ect ....those stuff are priceless ....and rare in other brands
The real deal is the Mercury ... that' s why i went for it ...when i was hesitating between Appolo + plugins versus RME + Waves ...and i don't regret at all ...cause even with what uad offers (at a crazy prices) i would have to still buy some "tools" ... (i don't even spoke about the lack of Windows driver support of UAD at that time ....i was told it will be ok for June (time of purchase january) and it was one year and half later !
