Personally I'd go with the bigger schools who have more resources behind them.
It also depends where you want your flying to go.
Basair for example is fantastic for people wanting to fly for leasure and PPL level, but not as great as you go further.
CAS is fantastic for CPL/ATPL/MECIR level, they have great theory instructors who will make life much easier.
Aerospace is good CPL/MECIR flying. The enviornment is relaxed and very firendly.
Basically people have to remember they get what they pay for, the more they are paying at BK, litrally the better quality training they are getting.
Those are the 3 big schools at BK and none of these 3 seem to be in a downtime at the moment, they all seem to be pretty busy.
