I KNOW I can get better sound into FOH with an IR than miking my cab. No question of that, I tested extensively. For that reason I used to use IRs, mostly OH, when I was gigging really actively.
However, I found I needed to limit my variety of IRs and use ones that resemble the sound of my cab, otherwise I couldn't get the preset just right for both cab and FOH. Finding good IRs is a whole other rabbit hole. Shooting my own IR of my own cab is one way to eliminate the rabbit hole, but it didn't sound any better than live-mic, and didn't sound as good as the pro IRs. So the only real benefit to my own IRs was not having to set up a real mic\stand on my cab.
When my corp band started winding down and later ended outright, I've found myself more often in jam rooms than on stages. With gigs few and far between right now, and with new FWs and new UR IRs, etc, I've dropped the cab IRs outright from my (so-called) gig presets. Now when I'm dialing in live jamming\gigging tones, I just use my real cab and eliminate the whole IR variable. It's SO much simpler and easier, and if I score a gig here or there as a sit-in or whatever, I can always mic my cab same as I've done forever.
If I ever get into a steady-gigging band again I'd consider IR direct again because it would be more worth the bother.
