My needs are very basic, but it just needs to do what it does well. A nice screen is nice. I like casual games like tetris and old-school arcaded games like Galaga, etc. I'll be syncing up my work email with a lot of pdf and possibly excel documents if that's at all possible. Ability to handle most downloaded tv shows from the bay. Also, I don't even know if this is an issue anymore, but a dedicated headphone jack would be nice. My phone needs an adaptor into the data jack. Lame. A phone that is a sucky phone is also lame.
I'm still using a Sony w810i (yeah, I know) so I don't have anything to compare.
The Captivate comes with an app for viewing and editing Office files, and has a beautiful screen. It's fairly solid, certainly moreso than the rest of the Galaxy S family, and gets good reception in my experience. The battery life is the best of the three smartphones I've had, with the stock ROM handling my heavy usage for a full day with no problems. It has video out via the headphone jack, but it seems pointless. It looked terrible on my 47"LG. This is to be expected since it's analogue at 480x800. It's so thin and light I had some difficulty handling it without a case, but I have smallish, fumble-prone hands. 16GB internal storage(about 14 available iirc) is nice, negating the need for an SD card for many. I never liked having the power button on the side, across from the volume rocker, but depending on how you hold the phone this may not be an issue for you. The Captivate is a bit more powerful than the Inspire, but I doubt it's enough that you'll notice in your described usage.
The Inspire, like all high end HTC phones, is like holding a magic stone. Slightly heavy, solid as can be, and with a just-slightly-less-than-smooth texture, I find it easy to hold and use despite being wider and a good bit heavier than the Captivate. The SLCD screen is nice and clear, with ok-ish daylight viewing, but falls far short of the SAMOLED of the Captivate on both fronts. I liked the small size increase, but it's not nearly as dramatic as going from 3.7" to 4", I find both sizes to be comfortable, but I miss the SAMOLED any time I use the phone in the car during the day. The reception seems to be a bit worse than the Captivate, maybe a bar less in low-signal areas, meaning 0-1 bar at work instead of 1-2. It has 2GB internal storage, but it seems to be reserved for apps and such. It comes with an 8GB MicroSD card(class 2), but I had to replace it with 16GB in order to be able to have any room after my music. Sense is a thousand times better than TouchWiz, if you plan on staying stock. The Dolby and SRS audio enhancements(only through headphone jack) are nice, and might make your TV viewing more enjoyable.
Overall, I am very happy coming to the Inspire from the Captivate, and plan on staying with HTC and avoiding Samsung because of differences in updates, software quality, and build quality, but both phones have their advantages and are good devices.
I've not had a chance to handle the Atrix, and I like the idea of Tegra and a high resolution screen, but I think it's ugly and locked bootloaders make kittens sad. However, the laptop dock, while expensive, would probably be very nice for your excel work.
I don't really know anything about the others listed, but I'd maybe look at the Surround as well, as I
think it has strong internals and WP7 looks nice and keeps getting better with updates.
