T110E4 Line

Been reading this subreddit for a while, decided to make my first post.

What is the general opinion on the T110E4? I'm at the T30 with the 155mm and I really enjoy it with a 2300 DPG and a 56% winrate. How does the E4 stack up against the other tier X TDs? Is the T110E4 worth the purchase once I unlock it?
