Well I got my first Anvil shirts just the other day (the kitty shirts!) and for the sake of, oh let's say experimentation, I had gotten one as ML and another as WL (as I had previously worn WXL and knew to go down a size).
My overall assessment is while they aren't bad shirts, they aren't as nice as the AA shirts. While I most likely won't stop buying Anvil shirts, I'll be more discretionary with what designs I get - especially with the price increase.
And here are some additional comments on the shirts, which I tried on without washing.
Fabric: The fabric of both shirts, as noted by others, is stiffer and I would say slightly coarser than the AA shirts. I much prefer the fabric of the AA shirts, but the Anvil shirts aren't bad. I probably wouldn't have noticed if I wasn't comparing directly to the AA shirts.
Seams: It may just be me, but the seam stitching around the top is very noticeable. It's the style of Anvil shirts, I'm sure, just something interesting.
ML Fit: It seemed a little smaller and tighter than the AA shirts. If it doesn't shrink much in the wash (which apparently it won't?) it will still fit fine, but I could see myself going up to a MXL to get a baggier fit.
WL Fit: Well, I must be one of the few women who doesn't really mind the women's shirt fit. But that's probably because I like wearing men's shirts, and not having the fabric hug my body. Because the women's shirt will likely never hug my stomach the way AA shirts do. I hear tell that's the style nowadays, so I completely understand why it's upsetting to a lot of the people who are looking for that style they used to wear. However, there are still a few things with the fit that are a bit odd. The shoulders are a little wide for me, so the seam on the shoulder puff up , especially when I lift my arms some. It looks like I have puffy shoulders, which is to say, hilarious. The sleeves are longer than the AA ones, which I don't mind too much. And the bottom 'hip' part chills out away from my body, as others have mentioned. However it's only an inch or so away on each side, so it doesn't look that bad. I'll see if washing affects the shape of this shirt much, such as fixing the shoulder issue. If not, I may try a WM shirt and see how that one fits.
