The most common position among members of the mainline Matthewite synod (the GOC-Stephanos) is that only our synod has grace. The ROCOR is considered by most to have been a schismatic body, which we erroneously entered into communion with under the misapprehension that they were True Orthodox. As for the Catacomb Church in Russia, only the communities under Fr. Epiphanius Chernov, who entered into communion with the synod in the 1980s, are considered canonical. We are also in communion with some Seraphimo-Gennadites in Georgia. Esphigmenou is a touchy topic, since they've only ever been in communion with the Florinites, but there's a great reluctance to label them as graceless or "outside of the Church" since that would be very unpopular. 90% of the True Orthodox of Cyprus are of the Matthewite persuasion, since Bishop Spyridon of Trimythus was the first Genuine Orthodox bishop consecrated for the island by Saint Matthew the New Confessor. Today, the autocephalous Genuine Orthodox Church of Cyprus is composed of a minor synod of three bishops, who are in communion with the Genuine Orthodox Church of Greece under Archbishop Stephanos of Athens.
Keep in mind these are not necessarily my own personal views, just the general opinion, as far as I can tell, among most of the members of the synod.
