The P210 is a great gun and has a cult like following. I have a regular one, a 50th Anniversary Edition, and a Silver Legend. When you ask if anything compares to it, you need to be more specific.
In terms of accuracy, many guns can be tuned to be as accurate, if not even more accurate. Few stock guns are MORE accurate, unless you get into semi-custom guns such as higher end 1911s.
In terms of trigger, the P210 has a nice crisp trigger with little take up. Again, many guns can be tuned or have trigger jobs so that they are better than a stock P210. Keep in mind that the P210 was meant as a duty weapon and not a target pistol (with the exception of certain models). As a stock duty weapon, the P210 has a great trigger. I have some 1911s with triggers that have shorter and lighter pulls.
In terms of history and significance, the P210 is up there. Other significant guns include the Luger P-38, H&K's P7M8, Browning Hi-Power. The 1911 is also arguably on that list as well, but they are still currently produced and run the gamut from super cheap to super expensive.
I would say the P210 is like a very nice classic car. They are great pistols with historical significance and command a hefty premium ($2,000+ for decent condition). You can get a gun that shoots as well (if not better) for close to the same money.
