I don't trust any of the gutter covers. I, too, HATE gutters.
I have drainage pits, so I'm pretty meticulous about minimizing the amount of leaves that I will allow into all the underground pulling that leads to my pits.
Instead of gutter covers, I installed some downspout screen/filters. like this.

it lets the gutters flow the water to the downspouts, but collects all the debris.
And then I gathered a variety of tools to scoop out the leaves from the gutters as they collect.
I like this, available on amazon and other places. I break at least one per year if I try to move too quickly with wet leaves, but attached to a long pole, I can clean 200 linear feat of gutters around my property in 10 minutes or less.

And half-round gutters are a gift from satan himself. never again.
