Hi Bob
The Grand Record looks to have more aggressive (racing) geometry than the CX bikes. It isn't a touring bike and doesn't say whether it has rack or fender mounts. The handling is likely quicker and more responsive than the others.

A lot of riders (including me) are buying Cross (CX) bikes these days for a do-everything road and trail bike. They usually have rack and fender mounts and a more relaxed geometry that may soften the ride and make it more comfortable but they may not be as responsive (less twitchy, more stable) as the other. The bigger tires are usually more rugged and not as prone to flat on rough pavement or through picking up road debris.

One problem with BD is that some of their bikes have last years' components. Both of the bikes with Sora shifters picture the old ones instead of the much improved new series. The latest have two shift levers like the rest of the Shimano line and I don't like the shift "button" on the old ones.

And I love disc brakes but don't care for the 8-speed 2303 group on the Gravity.

Since you haven't written that you're an experienced rider I hope you are planning to take the bike to a dealer to get it fitted to you. Getting the bike that fits you is actually more important than the difference in components.
Have you given your local bike shop a shot at earning your business?

I did prefer the older model.
I did give the lbs a chance to win my business however they are only interested in selling Treks. This is despite their carrying other brands and my asking about other brands/models to check out.

Yes, it obviously comes down to personal preference.
I have small hands and can only reach the thumb buttons when I'm on the hoods. I prefer the newer 2-lever design because I can shift from the hoods or the drops.
I use the drops for fast descents and like having both the gears and brakes at my fingertips.

I can relate to your LBS situation; my dealer pushes Trek though he carries other lines.
