I have a Mont Bell UL inner jacket (no hood) and I'm pretty happy with it. I have occasion to wear virtually every month of the year here in CO.
My sz L weighs 8.5oz and is still appropriate for me insulation-wise down into the 20's with a rainshell over the top. But still comfortable while drinking a beer on the porch in the 50's. I fully recognize that this is a function of the low humidity found in CO and would likley feel differently if I lived in the PNW.
The tag says that the Pertex outer is water repellent with a DWR finish, but I personally wouldn't wear it in precipitation more than a misting or light drizzle. I throw on Frogg Toggs or a Columbia rainshell over it if I need.
I've never found myself wishing the jacket had a hood, but I prefer beanies anyway, so that's personal preference. I do wish it had better wrist cuffs and a waist cinch though.
I'm really satisfied with mine, but if it got destroyed or lost tomorrow, After playing around with a firend's Eddie Bauer DownLight Parka, I'd honestly probably replace it with either that, or the DownLight jacket, solely for the elastic cuffs at the sleeves being superior to the odd triangle wedge of elastic on the MB. Only the hood would be in question.
Edit- to contribute to the OP's question: The EX and the UL are quite similar, the main differences being that the EX has higher Fill-Power down, and better wrist closures, but no hand pockets. The outer shells are a little different material, but still quite similar. I can speak to the quality of the UL, I'm sure the EX is much the same. Both lack a hood.
The EB FA would combine the wrist closures and hand pockets, but uses a heavier 15D outer, with an unknown fill weight and would weigh a touch more. Does have the option for a hood if you want.
I don't think you can go wrong with any of the three, or choices offered in other posts.
