Which is better for a 30A dryer circuit?

Both are 10/2 NM-B and work for a 30A dryer on a 240V circuit. Pick the Southwire if the run is under 50 ft. Pick the Cerro if it is longer or you want spare cable.

Is the Cerro worth the extra money?

Yes if you need more than 50 ft. At $136.69 for 250 ft it costs about $0.55 per foot versus about $1.68 per foot for the Southwire.

Can I use these outdoors or underground?

No. NM-B is for dry, above-ground indoor use. For wet or buried runs you need UF-B cable instead.

Does stranded versus solid wire matter?

Solid wire is stiffer and stays put in boxes. Stranded pulls through bends more easily. Both are 10 AWG copper and carry the same current.

Both are copper NM-B with similar insulation and should last decades indoors. The 90°C rating on the Cerro gives more headroom in hot spots.

Can I splice two 50 ft rolls instead of buying the 250 ft?

You can, but splices must be in an accessible junction box and add failure points. A single 250 ft run is cleaner for long circuits.
