I watched both of these shows when I was a kid, Grangehill I would say was better and had some classic characters, I like the Gonge, Hollo hollaway, Robbie, the original Bansky, Mr Baxtor, Mr Bronson, Zammo, Ziggy, Trev Cleaver days the best, Gripper Stepson was the evilest bully ever, it had loads of humour in it as well as being gritty. The grove I don't remember as well to be honest some names I remember Spuggy yes, Frazer her brother, some cheeky kid Winston, speedy, and of course PJ, Duncan and the best Geoff
