1. I love the automatic tiling, even if I 99% of the time only use it to have 2 windows split. It's just such a nice feeling not having to tile windows each time you open them up.
2. It let's me set programs being tied to specific workspaces at launch, so I always get spotify and discord on the first workspace on my second monitor. Again, a nice qol feature.
3. I think komorebi's workspaces are more powerful than virtual desktops. In virtual desktops then you change the desktop for both monitors when you switch, with komorebi you only change one monitor at a time. Which allows me to for example keep a youtube video on my second monitor playing while switching between workspaces on my main monitor.
These are probably the main reasons, I mention most of that in my youtube video that got linked in the thread.
I've long been happy with what Windows provides natively. I kinda wish that Win-Z provided a few more horizontal split options that make sense for 32:9, but reality is that I have Fancy Zones installed to provide the layouts I thought I'd like but I never use them because it's usually for console stuff and Windows Terminal has its own tiling system.
Sometimes one makes more sense, sometimes the other. Fortunately, I can use a tiling manager with multiple monitors if I want.
But, I can use a tiling manager on my laptop anywhere multiple monitors are impractical. For me, that’s most places. YMMV.
I think some people like to have specific configurations like "open these 4 programs in these 4 positions" though.
