My small ISP is unbelievably reliable. Maybe FTTH is better than old school BB. But they resolve issues quickly, if there is one.+1 to this
I'm myself using an airtel 40Mbps copper connection (not fibre). My only issue with it is low 7Mbps upload speeds which is annoying when I try to upload files. For gaming, it gives me better latency than Excitel fibre in my area, but excitel was offering like 100Mbps up & down for like ₹50pm more. Opted to stay with airtel for the lower latency. ACT is too expensive.
I'm not sure why many areas in Bengaluru has just copper for airtel. Many of my friends are using ACT just because airtel doesn't have fibre in their area & they don't trust small ISPs regarding downtime.
