The germans did have some tanks in service that are good and strong compared to the allied tanks and russian tanks specially in the first 2.5 years of the war.
In the beginning of the war the germans did have enough very heavy tanks that the allies could not match remeber a Tiger tanks? for example
They really did kick ass in the starting of the war and even in the end of the war these tanks did maintain there status as badass and very strong foe.
Specially in the hands of some skilled crew they could be devastating as history clearly shows.
but after some time the American tank industry put all the battle field knowlegd into new types and design's that could match or even outmatch the german tanks and armoured vehicles.
The Maus:
The Panzerkampfwagen VIII Maus (Sd.Kfz 205) was a German super-heavy tank design, and the heaviest tank to reach the complete working prototype stage in World War II. The basic design known as the VK7001/Porsche Type 205 was suggested by Ferdinand Porsche to Adolf Hitler in June 1942, who subsequently approved it. The design up to then had been the culmination of work done by Porsche who had won the contract for the heavy tank that March. Work on the design began in earnest; the first prototype, to be ready in 1943 was initially to receive the name Mammut (Ger. "Mammoth"). This was reportedly changed to Mäuschen (Little Mouse) in December 1942 and finally Maus (Mouse) in February 1943.

As i already wrote the Allies and Russian learned from the early war where germany did have a huge advantage but after a few years battle this advantage was shrinking due the ever increasing numbers of weapons that put into service to remove this madman.
But also the way the tanks did get build changed very rapidly and they got more advanced by the minute so eventually the allies beat the germans not only with numbers but also with better technology.
But the germans did made some nice stuff and the Americans for example did try also to create there own version of the maus because you must admitt that if this tank could be build in a more mobile way than it would be certainly
a badass tank that really kick ass.
Anyway here the US version of the maus:
The T28 (later called 105 mm Gun Motor Carriage T95) was a prototype heavily armoured tank destroyer, designed for the US Military during World War II. It was originally designed to be used to break through German defenses at the Siegfried Line, and was later considered as a possible participant in an invasion of the Japanese mainland. Although sometimes referred to as a super-heavy tank the T28 was, in reality, a very heavy tank destroyer, and was re-designated as the 105 mm Gun Motor Carriage T95 in 1945. In 1946 it was renamed again, to T-28.
The T-28 was designed and manufactured by Pacific Car and Foundry Co. The original plan was for five prototype vehicles with a production total of 25.However only two were ordered and neither saw combat. One was heavily damaged by an engine fire during trials and was scrapped. The remaining prototype was discovered abandoned in a back field at Fort Belvoir. It is the only remaining example of these tanks and can be viewed at the Patton Museum of Cavalry and Armor in Kentucky. Its total weight when fully equipped would have reached 95 short tons. Because of the tank destroyer's great weight, it used four tracks instead of two, at 12.9" wide. The outer tracks could be detached for easier transport. After removal they could be fixed together to make a unit that could be towed behind the tank.

I could not find a Russian version of this one but iam sure that there would be one that fit these specific's because the Germans and Americans/British did have a ton of new type's, but the Russians went crazy with building all type's of new weapons they produced so many that it is hard to say what type actually matches this German Maus.
