I've worn tapered Cirrus and liked it. They had a batch with oddly large buttons for awhile. Dunno if they've swapped stock for regular size shirt buttons; ya might ask.

The new issue M&H shirts aren't bad and take a good crease thanks to the poly/cotton blend, just a little baggy. Definitely better than the Twin Hill cotton. They advertise a tapered cut one that I'm tempted to try.
