TGV is ok, I liked him a lot more when he just started his channel, used to review only affordables and did a lot of collaborations (e.g. with Federico). Then he got famous, started falling out with other youtube personalities and in general started behaving more like a snobbish dick. I still watch him from time to time but only if the video is about something I'm really interested on.
On a side note, my favourite watch channel on youtube, by far, is watchfinder: amazing camera work, a voice worth of a documentary channel, and always an interesting story or take on the watch at hand.
Tim's reviews on the Watchbox are also pretty good, but they are just that, a bit dry IMO.
