They do. Here's the RJ quote to prove it:

It isn't just that the strongest woman and strongest man are effectively equal despite a difference in the volume of OP they can draw. It carries all the way through, or there wouldn't be 2.9% of the male population that is technically strong enough to be Aes Sedai strength, but not effective enough to be considered so, if such limitations held at the BT.

But are the men at the lowest rungs effective channelers at all? We've seen Morghase be able to do some small things. Can men at that level do anything? I doubt it. For all intents and purposes, all they have is the ability to rarely touch the OP, and increase their lifespan. Whereas Morgase is proof that women can actually use that puny strength to affect the world, if in incredibly small ways.

If Naeff could draw as much of the OP as Aviendha, he wouldn't be able to have as much of an effect as her. Granted, he is strong in Air, but its not like she's weak in it.

This is pure wish fulfilment. We have no way of knowing what she meant on his actual strength. We knew he had been previously forced, and we knew he could make a usable gateway. If, in a matter of weeks, he jumped up even one level, that is remarkable by Aes Sedai standards. So he could have moved from an effective level of 19 to 18, and that would still make Merise worry, as he is young, and could potentially outstrip her.

The listing of a circle seems to be a pretty clear pointer that the strength levels being listed are for women.

But a man of strength level 19 wouldn't be as effective as a woman in that level. There are entirely too many quotes that prove just this.

I suspect some are stronger, like Flinn, but I would just change that number to level 13.

There is no evidence that women's dexterity bonus has a scale. None. It seems to be a constant thing, if you look at all the quotes.

Take the RJ quote I posted above. If there is a dexterity scale, the numbers would be much more complicated. RJ would have to make a caveat for a man who is as strong as Daigian in raw strength, but more dextrous than most men, and therefor effective enough to be "Aes Sedai". But he doesn't. He clearly says men who are drawing as much OP as the weakest Aes Sedai would be too ineffective to technically be Aes Sedai.

Nope. We just don't know that a level 66 man can do anything. We know of someone who is either level 66 or very close to it who can actually move a handkerchief. A man of that level will simply be unable to do anything useful, per RJ's statement. Or maybe he can only mildly budge a fly. Point being, there is no equivalency in the lowest level beyond raw OP strength. They are clearly not effectively equal.

As for the lower levels below ++1 and 1, clearly there is an equality, and that goes all the way down to the female level 45, which is more effective than the male level 45, per RJ.
