I've used EZY many times and always found them to be professional.
Yes you have to hang around a bit but a recent aircraft change at LGW was handled efficiently with a total delay of 20 mins.
Some of the cabin crew are young but not all and at least they do not bombard you with PAs.
All and any airline could do with sharpening up service skills! Easy makes a pretty good fist of it by and large.
On a descending scale I reckon they come just under BA; sort out the herding, where it exists, and they'll have it sorted.
