I have encountered several problems comparing with Java Edition:

1.  it is impossible to place torches where there is water. In Java Edition it is possible, even if the torch is removed immediately afterwards, this allows you to recover air in Survival.
2. it is impossible to put objects like torches, arrows in the secondary hand ... In practice only the shield can be placed.
3. In Creative the bucket of water empties when you place something water. Sometimes you can go on indefinitely, other times (as in survival) the bucket empties with each use

Thanks,
