Washington, Lincoln, and for some FDR are greater on account of immensely challenging crisis issues they overcame. Teddy was simply glorious.
Square Deal Domestic Policy: TR's DOJ launched over 40 anti-trust lawsuits on corporate monopolies (taking down the likes of J.P. Morgan's Northern Securities Corp and ultimately John D. Rockefeller's Standard Oil Company). If those guys didn't own and control you at the turn of the century, nobody did. He enacted the first significant consumer protection laws in US history (Pure Food & Drugs Act, Federal Meat Inspection Act, Hepburn Act). He doubled the number of national parks, declared the first 18 national monuments, created 55 national wildlife refuges, and established 150 national forests for a total of 230 million acres of federally protected, publicly owned wilderness.
Big Stick Foreign Policy: He secured the agreement and initiated construction of the Panama Canal to greatly enhance American geopolitical power and global commerce. He brokered the Treaty of Portsmouth to end the Russo-Japanese war (and won the Nobel Peace Prize). He organized the Algeciras Conference to relieve tensions between Germany and France. He substantially upgraded US Naval power and projection, sending off the Great White Fleet. He didn't start nor send any American son to war, despite the fact that all four of his own would go on to serve in World Wars with great distinction and three of them didn't make it out alive.
Borderline Flawless Presidency.
