There's no mention yet of "durability" - as in "longevity" in these critiques.
How a cloth "plays" is important; but will it need to be replaced in two, three or ten years - is also important. Then too, wool has some interesting properties. For one, it has a high melt point. We know ball spin friction, creates fade marks on the cloth. That's from the relatively high temps generated by the point of contact being so small and the ball spinning at high speed can induce "burns."
Wool also is least affected by overall temperature. The contraction and expansion rate of synthetics is huge - compared to wool. On extremely hot days, synthetic cloth will tend to be "looser" than wool. Conversely, on cold tables, the cloth will be tighter than wool.
If you play often enough to bother with a cover, sunlight will be a factor. Wool vs. Synthetics will react to sunlight quite differently.
Then there's the money angle. The cloth is one thing and anyone with a web browser can see who's got what fabric and at what cost. Comparative shopping allows us to determine what prices various coverings are. The labor however is roughly the same to recover a tabe - regardless of the material selected.
A great cloth installed by a butcher - is far worse than a cheap cloth installed by a wizard.
As yet undiscussed - despite being critically important; "how much play does your table get; what's the room temp swings and humidity levels typical for 12 months and; does sunlight hit the playing surface often enough to be a factor?
Lastly, covering the table when not in use has both pluses and minuses. If sunlight is an issue, covering may reduce "bleaching" but at the increase of the sun's rays being converted into trapped heat - making the cloth beneath the cover, even warmer then not having a cover at all. That problem could be reduced or eliminated by putting a UV "shade" on the window(s) that allow the sun in, or perhaps blinds.
Also, if you have hot air heat - and/or central air, lots more dust will be on the table.
While we're on the topic of cloth, "brushing" - recommended by almost the entire planet as the "proper" way to keep the cloth clean - is an absurd notion! Brushing cleans nothing. It merely evens out the distribution of dust so the whole table top remains flithy!
At least four times a year I use the brush attachment to the regular house vacuum and carefully and slowly vacuum the entire table, under the cushion angles and cushions themselves. I have looked at what the vacuum picks up and cannot believe anyone would suggest that brushing alone is "good maintenance."
