I'll be one to put my hand up and say I used it, like it and trusted it. I used 2 F4s and my partner used 2 F4s, with both AF and MF Nikkors for about 5 of the busiest years of wedding photography in the late 90's to mid-00's. We put hundreds of rolls thru them monthly, and after a few months of trials on weddings we used Matrix pretty much exclusively, mostly manual but a good chunk was on Aperture preferred Auto. Fast changing light for outdoor ceremonies I preferred it. Matrix Metering made very consistent and very CONSISTENTLY good negatives both color and Black and White. Very seldom it would blow an exposure; even the bad exposures were savable with a bit to darkroom work (what a concept! LOL).
During my days as a news shooter I saw a staffer at a new service show me what an F4 could do at a football game. He shot a play of a running back going from full sun full background illumination to full sun on the running back with the background shifting from full sun to full shade to the running back ending the play in full shadow; one long sequence of perhaps 13-15 frames. I saw the actual color neg film and each frame was *perfect* exposure, he shot with a Nikkor 500mm f/4P in of course Manual Focus, the F4s was in Program High! with Matrix Metering. He was a very good sports shooter and said that was what the Matrix Metering is for; changing light and backgrounds in moving fluid situations, exactly the type of situations where the shooter either didn't have time to handle a complex metering calculation OR learned to Trust it. I learned to trust it, even if 40-50% I was in Manual exposure. When my shooting got very fast the quick shifting of the mode lever on the F4 was a huge help; one flick of the lever from M went right to A, not like the F5 (which I use as well).
So that's my thoughts: I started with Olympus OM-2 Spot, OM-3 and OM-4t with their version of averaging multi-spot so when I switched to Nikon I wasn't thrilled to move to what I thought was inferior and simpler Center Spot of the F3 and the 60/40 of the FM-2, so had a solid set of exposure skills before I got to using the F4. I like Matrix and have used it enough over a long period of time to trust where its most useful. I still use my F4's although not as much, 2 have the aperture lever issues but the other 2 run like champs. I'm not saying Its For You but it works well for me.
