Help me decide

I am looking at the following bikes and needing some opinions from those of you who race.
GT Grade Ultegra
Fuji Altamira cx1.3
Jamis Renegade Expert

Prices being equal for the ones above, opinions for gravel racing with occasional CX race.

Is the Fuji too much of a CX bike for Gravel racing?  Can the GT and jamis be used for CX races?  new to the gravel riding aspect so please assist.

Or the items below for the same price, about 800 less than the ones above.
GT Alloy X
Jamis Exploit

I was just searching for a bike on behalf of a friend and saw this - not sure if this would work for you but think it's a very nice spec and a great price.

And if you buy when they have the 20% Performance Points promo that would be worth and additional $400 for a net of $1,600.

I've ridden the Jamis Renegade Exploit and Renegade Expert. They're almost two completely different bikes due to the frame materials. The Exploit is chromoly and felt more like a cruiser to me. I thought it was rather bland all around. The Expert has the carbon frame that is like driving a Lexus. Very smooth and comfortable with some decent performance. I think it would make an awesome gravel grinder since it soaks up all the road buzz. But, like the Exploit, it's not a quick handling bike at all. I wouldn't recommend either for racing.

For me, personally, if I were going to buy a bike for CX racing and gravel grinding, I'd probably look at a Giant TCX Advanced Pro 2. Altho that will be a few dollars more. I've never seen the Fuji or GT, so I'm not doing a comparison with those. Just giving you another to consider.
