Which phones have the best coverage under T-Mobile?

Samsung Galaxy Note 5 Gsmarena

I am currently an ATT customer with 2 iPhone 5cs, 1 LG G2, 1 Samsung Galaxy Note 3, & 1 Samsung Galaxy Mega 6.3 (which are all directly from ATT).

If I move over to TMobile, I want to make sure that I am receiving the best coverage possible, as there is all this stuff regarding different bands. I live on Long Island in New York, and regularly commute to New York City. I also sometimes commute to Philadelphia.

If I directly bought phones from TMobile, which phones are known to have good coverage/signals for TMobile? iPhone 5s, LG G2, Galaxy S5? I think that I should just sell the ATT phones, if they are going to have worse coverage. Also, I think the ATT ones sacrifice wifi calling, if I am not mistaken.

Lmk your thoughts! Thanks!
