Just read some reviews on MAS business class and heard its not really worth it

The angled flat beds are not that comfortable apparently...
Not sure what to do...
Will maybe wait until April and see what BA offer then
Thanks everyone for your help
EDIT: Just seen that on their A380 the business beds are fully flat. So will look at which planes its offering. Maybe I'll just do Business on the A380 leg of the trip.
How do I book award seats / upgrades with Avios. Must I call BA or Malaysian?
