Would choose Tayflight because of the uncongested airspace. At Leeds you have to book the beacon and with the summer season starting soon the airport is going to get very crowded with commercial traffic.
As for Henry Crowe ex BAE flying training at Prestwick !! Mega proffesional he trains you to fly like the airlines require not just to bash a test route to pass the IR.
As for Multiflight well ? Great at taking your money of you and then treating you as a leper when you revisit the place at a later date.But turn up in a shiny jet they are all over you. Come back the good old days of Knight Air!!!!
End result I would choose Scotland less congestion allways ends up in more hands on flying instead of wasted mins at the hold or orbiting.
I wish you well in your choice and hope you enjoy it when you finally get on line with your first job!!!!!
