Got rid of my BAPP, when the 241 spend threshold increased. Frankly, some sort of increase was bound to happen after do many years at 10k.
Have the Marriott, which is my favourite card to use day to day as find the points useful.
The Biz Plat is great. I manage to hit the monthly 10k spend most months, so get effectively double MR's on that spend. Also used the travel and Dell credits.
overall, I've not found the service to have declined over lat 18 months. But offering needs to improve.
