The High 5 in Dallas would be the most massive. Its a monster, literally.
As for having the most impressive freeway stacks overall...
1. Los Angeles
2. Houston
3. Dallas
4. Atlanta
In that order
I would put Miami over Atlanta. No dig at ATL but South Florida has a lot more and those raised HOV lanes are impressive too.
A lot of ATL's main freeway intersections have quite a bit of the old cloverleaf design.

Northeastern US doesn't have very many impressive interchanges though oddly enough Albany, NY does along I-787 & I-90

Every time I see I-90 in NY it just amazes me a bit... I've taken the Thruway from Syracuse to Buffalo a few times in the past.
The whole amazement thing comes from the fact I live about 20 miles from I-90... where it crosses the Cascades at Snoqualmie Pass just outside of Seattle.
I guess from an infrastructure stand point, clovers are pretty efficient, but I think stacks are better for the driver.
One other poster mentioned that in a cloverleaf, you basically have to slow down, take the curve, then floor it to merge back into traffic while also avoiding traffic going into the next ramp. That burns a lot of gas and to be able to do it without slowing down too drastically would mean the interchange would have to be way large. That's probably why cloverleafs are probably more prevalent in suburban and rural areas.
Clovers useful for Freeway to Road interchanges...not so much for Freeway to Freeway. Especially if either freeway has high traffic. And especially if you're trying to save space within the city.
...
Then again, some of these spaghetti interchanges make my head hurt and wonder who the hell designed these freeways.

Cloverleafs are the interchange of choice in the Twin Cities, much to their chagrin, and are not the suburbal/rural exception -- they are the RULE throughout the metro and the city. It is UNREAL how poorly designed this is!
Yea, they look gnarly on Gmaps. Someone obviously had a fetish. I wouldn't even trust myself to make it through any of them with how close the exit and entrances are to each other. I can only imagine the horrible scenes during rush hour.

I counted 22 cloverleafs of some variety in the Twin Cities. This is after a few have been removed and redesigned, too.
The ~18 mile stretch of 169 from 494 to 610 has 8 of them alone...
