Not only does Doom play well but Quake is playable as well, and Shapeshifter absolutely flies with an RTG-card. Marathon, Warcraft II, Links LS and SimCity2000 all play really nicely.

The one metric 040 wins clearly these days is performance / dollar ;-)
But one important thing to understand is that the 060 is a dual instruction pipeline design, so in theory, running perfectly optimized code, it could retire double the amount of instructions/clock cycle compared to the 040. But that's in theory..
Software that doesn't do anything to utilize a dual instruction pipeline will run similarly at same clock on 040 and 060. This is still noticable today.. I have a 12 core, 24-core thread Ryzen in my PC running at ~4GHz. But if you run a single threadded benchmark it will lose to a quadcore Ryzen (of the same generation) that runs at a higher clock.
The other thing to remember is that getting the CPU to run at a higher clock is also an option when chasing more performance. 486 was technically worse / clock than 040 but would clock much higher. There's a reason there was never any 040 faster than 40MHz. In comparison, even the rev 1 060 could run at 50MHz without cooler. And as we know, last revision clocks to 90-100MHz.
So these are things to consider when you compare 040 to 060.
That being said, I'm pretty certain that a 40MHz 040 is what would give you the best bang for the buck in terms of overall processing power (CPU+FPU) on your Amiga.
