This is an excellent thread. I can relate to this this very well actually. Upon deciding which flight school to go to etc, I decided on Bournemouth Intl (Solent school of flying) for many reasons, quality of instruction, prices, type of aircraft flown and busy class D airspace which gives the student great experience.
My instructor was a top bloke, really liked him and he was a highly skilled professional who has flown here, there and everywhere! He now flies in an airline job and am very jealous!!
I thought we got on OK but when we were in the air, I felt that my instructor kind of sucked the fun out of flying for me and I started to not enjoy flying.
So I thought of changing instructor's but he left anyway.
