FWIW.
My former Verizon DSL over the copper phone lines.
AT&T 4G 'hotspot'
Another showed similar download, slower upload but still very good compared to Verizon over the copper.
Ping is a little less consistant with the 4G wireless, and they have the right to choke it if I use more than 22 GB a month.
I'm nowhere close, and have no need for FiOS speeds (and associated cost). YMMV
