Solid vs Stranded, Wire Nuts vs Wago

When it comes to using THHN wire is there a preference of solid vs stranded? I would "think" solid is superior.
Any pros and cons of one vs another?

Separate similar preference question - traditional wire nuts vs the push in Wago type connectors - Is one considered better than the other or purely preference?

It all depends on the application. The stranded is much easier when it comes to pulling in conduit especially with multiple sweeps/elbows. The solid is much easier to attach to devices. A novice would find solid wire easier to splice.

I don't use Wagos. Strictly wirenuts.
They accept stranded and solid wiring but they are easier to use with solid wiring.
It can be tough to get all the strands into the connector.

Solid is easier to push. Stranded is easier to pull. Stranded is harder to wrap around a screw terminal. Solid is slightly smaller for the same gauge.

Wire nuts are dependable, tried, and true. For larger ones use the winged versions so as to get a good grip. Wago style can be easier for joining 3 or more wires. Some brands the wires can pull out easier than others but usually not an issue. Some only take stranded in one of the slots.

Don't ask about wall receptacles. Ground up or ground down discussions are banned in some places.

I have been known to tin stranded on occasion. It makes for an easier connection to lugs and in a wire nut.

It is ok to tin the very tip of stranded wiring but the tinned part should not be under the screw as the solder will compress/cold flow in the future causing a loose connection.
