OK here is my 2 cents.
I also have the Aerostich Combat Tourers (made by SIDI). Fabulous with a capital F. Always comfortable and naturally water resistant. The only time I got water in them was after 13 hours of steady riding in a steady rain. They are comfortable and very easy to put on and fit very well under a shift lever.
They don't have any funky new wave water membrane, but I don't think they need it. They can get a bit warm if you walk in them a lot on a hot day, but I am usually on the bike. I have worn them in every weather and they work everywhere.
I would buy another pair in a heartbeat. However, after now having around 60,000 miles on them, I am not sure I will ever have too. They still look nearly new. Fantastic. Andy G., I will be back!
