is the E75 TS worth its gold?

[Catweazle]

Hi, i have, thx to the last event, saved enough gold (6500) to buy the plain E75 TS.
Or i could just save a load of gold, buy the Dicker Max for 2000, which comes with 30 days prem, special camo and fully equipped. Which leaves me with some gold for the next good offer.
So, what is your experience with the E75 TS? When i first saw it in battle, i was impressed. Better armour than the Tiger II, nice gun and still able to move. When i check the stats, the winrate its higher than Tiger II and Löwe, so i am really considering to spend all my gold to this one tank.
And there is one more thing. As i was very satisfied with the IS-3, i was happy when my clan reaches tier 10 and i could get the IS-5. And then i realised that this tank, which was my most feared tier 8 enemy, was not that good and i did not get the grasp on it. My VR IS-5 to IS-3 is 5.5 lower :(
