Jio has been working fine up to now, though it hasn't been very long yet so I can't say for the long term, the customer support thankfully is helpful and answer your calls quite quickly instead of very long wait times on airtel unless you are black customer, the fiber maintenance is not done by a third party but they themselves. I have a direct number with my local engineer and he is helpful whether it's an infra issue or technical.
In my complex JioFiber came a lot before Airtel, but their infrastructure has been clearly maintained a lot well compared to if you see airtel almost everything is either broken, half mended, etc. You don't get so many loyal customers if you don't have good uptime and a good service commitment (as I have said about 70-80% of households here use Jio).
I sometimes (like 1 or 2 times) see lower upload speeds when using speedtest, but the same was not true when I was actually using the upload capability.
On the technical side of things, I haven't had any web performance and steaming issues yet and everything has been working pretty fine actually, except the FTP issue about which the NOC Chief has personally contacted me to discuss and identify the issue.
I don't do much multiplayer gaming, but I recently played some CSGO and Wildlands with my peers and it worked quite well. I have UPNP enabled on the ONU and I'm getting Open NAT in almost all games and applications even torrent works quite well and I'm receiving incoming connections from leechers/seeders. When I'm out of my house I sometimes use SteamLink to play games, going through diagnosis it seems I was directly connected to my computer (P2P) instead of using the Steam Server Relay which improved the game experience.
I used to have a lot of connection issues with Ubisoft on airtel but there does not seem to be any with Jio and download speeds when using battle.net is insanely better, the same goes for Origin and Steam (Steam, if I'm connected to an airtel cache server).
Last, ever since the Jio STB came my parents and if I ever receive guests are hooked on it like crazy. So, I doubt I'd be able to disconnect it anytime soon anyway. My grandma finally comes to see me, since I have means for her to see her favorite
TV shows.
Hope this was helpful, but again you might have a completely different experience in your loco, I'd suggest giving it a try and test if it's to your expectations.
