X-Limit

I own most of the SSL X series and a few of the 360 plugins, and X-comp is immediately my very favorite bus limiter for most projects. If you A/B test the sound signature of this limiter vs for example the native steinberg limiter, the bx_limiter, BWS 5.2.7 native limiter, or NI's limiter, especially when gluing a mix, the X-limiter has a noticeable 'sweetness' and 'musicality' to the sound post-process that is not as prominent in other (simpler, less dynamic) limiters Ive used.

I do not own any hardware approximations of these plugins nor do I have too many other brands in my library, but the few widely used limiters I have do not sweeten or glue the sound as well as this. The visual waveform display with color mapped limiter activity is a really nice visual way to check on your mix as well, and I really appreciate the sound signature, UI/UX, and processing load of these plugins. 5 stars for sure.
