Comparison of operators by LTE quality

Question

Megaphone

Welcome all. Guys, I've decided to change the operator, but I can not decide who to take. I choose 4G, who has the best. I'm from Khabarovsk. So, as far as I understand, the beeline in my city does not have 4G at all, only in Moscow. The megaphone and mts in my city have coverage, and I can’t choose from them. On the Internet, opinions differ, some say that the megaphone has more coverage, therefore more users and therefore less speed. And on the other hand, MTS has just begun to develop in this direction, and vice versa, MTS has a lower speed. And I'm confused, correct me if I'm wrong and tell me who better to join?
