Yeah. But the crown jewel of the Russian Navy are the submarines, no?
The answer is both yes and no, dependent on what you mean.
To answer this questions requires to go back over a century and look at Russian naval history and traditions, of which it barely has none. Navies are one of those things which relies on decades and decades of culture and traditions to be set within a group of sailors for it to be effective. You can't just hand some sailors a state of the art warship and expect it to perform well. This has been proven time and time again, for example during the Napoleonic wars where French ships of the line with more cannon, thicker hulls and larger sterns were being beaten in 1 on 1 combat with British frigates. This really came to fruit during the Russian-Japanese war at the battle of Tsushima strait where state of the art Russian battleships were brutalized by Japanese warships, because of ill discipline, lack of sailor culture, institutional knowledge and poor training.
This defeat basically ended all Russian hopes of having an "Imperial Global Navy" and with the onset of WWI, it was further stepped back. By the time of the Bolshevik Revolution and when Stalinism really kicked in, the Navy was all but abandoned. During WWII, of all the threats the Soviet Union faced by the Wehrmacht, the Kreigsmarine was not one of them, so again, there was no real development of naval warfare on the surface ship level. All their major surface combatants were hand me downs from either lend-lease (for example, HMS Royal Sovereign) or relics and pre-dreadnaughts from the Russian Empire days. What they did manage to build was domestic submarines, which played a part well during 1944-45 when the Germans tried to evacuate the Baltics and East Prussia.
Come the Cold war, the Soviet Union knew they could not even try to attempt to outmatch the NATO fleets on surface combatants. So their doctrine was very similar to what Germany did in WWI/WWII. Have a surface fleet that was large enough for it to be a reasonable consideration (essentially a Fleet-in-being, much like Scheer's WWI High Seas Fleet) but have a horde of submarines breach the NATO lines at the GIUK seas and cause havoc within supply lines in the Atlantic Ocean. (it was actually more nuanced than this, with late cold war the Soviets realized that breaching GIUK was impossible). With this setup, funding and money was thrown into Submarine warfare development much more than surface fleet development. This also forced counties, like UK, to focus much more on ASW as opposed to ASuW, hence you have embarrassing situations like the Falklands where the UK were ill equipped to handle low-flying anti-ship cruise missiles.
When the Soviet Union collapsed, all of Russia's military suffered a budget crisis, the navy included. Everything was scaled back, but because there were so many submarines and subs were the one thing that there had been decades of institutional knowledge bought in, Submarines were the ones that managed to recover the quickest and actually further their development lifecycles.
Since 2000, Russia has put forward 23 "modern" Submarines into its fleet. It has put 0 "capital ships" on its surface fleet (atleast the western classification of them) and the best they could do is bring out some semi modern frigates.
So if your question was "Are the Submarines the best ships of the Russian Navy compared to a global standard?" The answer is Yes.
If the question was, "Is it fully intended to be that way?" The answer is, no.
Submarines on their own lack a lot of strategic and tactical flexibility - this was why the Soviet Union still had a very large Surface fleet. The flagship of the navy has never been a submarine because, quite simply put, a Submarine does not have the necessary facilitation for flagship operations, it lacks command modules, integrated command and control sensors and datalinks to aerial assets or battlefield control modules.
The crown jewel of a navy should always be a surface vessel, but because of institutional stagnation and a lack of focus, the Submarines are the best Russia has and right now their flagship is the Makarov in the Black Sea Fleet. Ultimately, a frigate is going to miss a lot of facilities for proper command and control, but it's much better than a Submarine. Their previous flagship, the Moskva, was sunk over a year ago.
