Metric does not suck. It would take some time to adjust to thinking in terms of kilograms instead of pounds and kilometers instead of miles, but the Base-10 metric system is vastly superior to the Imperial system.
Here’s everything you need to know about which one is better - the British developed the Imperial system and the French developed the metric system. The British have since abandoned their own system in favor of metric.
When the British concede that the French did something better than they did, you can book it.
I dunno. All my metric wrenches slip and foul the edges of the bolts, but that never happens with good ol' English sized wrenches.
Is it possible to be too precise?
