The answer to the question depends on what the question means, and that isn't clear at all, at least to me. And a lot of the answers, since they involve courses I've never seen, don't help me understand either the question or the POV of the answers. So, since I just got back from Streamsong, and since there are at least some similarities between the sites, I'll just use Streamsong.
The question COULD mean making use of an unusual site, such as the old quarry site that is TR. In which case, the Blue course at Streamsong seems a much better comparison than the Black. When you have to walk up to the first tee at the Blue course, it's a little bit hard to believe that you're in central FL, given that the highest point in the whole state is less than 400' above sea level. Much like the first hole at TR, or the 13th green, I don't think much dirt had to be moved to do that.
The question COULD mean a course that looks much harder than it actually plays tee to green, and then provides tremendously varied greens that are wildly fun to putt, in which case the Black course is a much better comparison to TR than the Blue.
The question COULD mean a course than generates a "love it or hate it" reaction, in which the best answer at Streamsong would again be the Black, but since I dearly, dearly love Tobacco Rd, and dearly loved each of the Streamsong courses, I'm a very poor candidate to answer that question.
But above all else, the key point to me is that there just isn't anything really comparable to The Road except in somewhat superficial ways. This course or that course is similar, but more is NOT similar at pretty much any course you can name. Even Mike Strantz's other courses are only similar; when speaking to people that haven't played it, I always refer to True Blue at Tobacco Road at the beach, but that is VERY superficial and therefore limited.
Here in NC, #2 and #4 have visual similarities because of the sand and waste areas, but the greens couldn't be more different than TR's greens. Southern Pines is probably now a better comparison than either #2 or #4, but still not perfect by any means.
This won't be a surprise to anybody, but I feel a bit sorry for those of you that don't like Tobacco Rd, if that's your perspective in answering this thread. I can't get enough of the place, perhaps in large part because I've never seen anything like it. I just laugh the whole time because it's so exciting to me, and I've had great rounds there, and I've had rounds where I wasn't sure I would have enough golf balls to finish.
So I suppose my final answer is that it's a BS question. Sorry...
