I watch both of the guys, each one has his stronger and weaker points,
Peter - He is i think around 80 years old, he has a lot of expirience, but i guess his show trees prime time is gone, as someone else said, he went more for commercial aspect now, no time to focus on couple fo trees. i watch all his videos and aleways find some good advice or something to think about. There is no single doubt about what he is doing, he has done in the past and worked for him, the only aspect i dont like - he is mainly working on maples. He really loves nature and trees, you should see his face being around that massive old Yew tree, you can see passion and love. He has done a lot for bonsai world, he should be treated with respect.
Nigel - i think his my favorite guy to watch, i guess he is the only person that is honest and shows/talk the trees that died on him, ive never seen anyone else saying/showing trees that didnt make it. He has a knowlege and expirience, he know how to pass it on, his natural behavior and the way he talks makes him really pleasant to watch. Also i like to see his work and involvment in community work etc, he is very excited to do it also.
I cant stand the vidoes that are looking like from hollywood productions, it looks fake and artificial to me and mostly they will work on very old refined trees that needs more likely only more ramification and maybe repotting, dont get me wrong its interesting to watch but thats not im looking for. I like Nigels vidoes simply because he shows trees in different stage of growth, did you see anyone else planting seeds ? He has advice on each stage of growth and uses clip and grow which is very intersting too, its natural way.
Anyway that was me
Think twice before you do the same what was on the video
