They've improved and matured over the years. When they first started, yeah, they could be catty. I remember Terry Gannon getting sort of exasperated and trying to rein them in a bit. And they talked all the way through the programs so you couldn't hear the music or just enjoy it. But they've gotten better at shutting up and only talking about important points.
That said, I have Peacock and I have infinitely preferred their venue/world feed which has either no commentary or very limited from some British woman that I don't know. But she's generally very quiet.
