EE good network?

[JHONO]

Title says it all, are these any good in terms of coverage, 4G, customer service etc? As thinking of getting the new S6 with these?

Thanks

Coverage seems excellent in my area, according to the checker on the EE website.

After googling though, heard people saying on reviews they have been overcharged on bills etc. I don't know if its just sour grapes or something they have done wrong on their part. Always been an O2 guy but their 4g coverage is average compared to EE imo.
