What I noticed is that if the coin is dropped due to mempool congestion making the purging to be greater than the fee rate used, or the transaction is getting longer than 14 days that most nodes would have dropped it, some nodes can still have it because nodes can change the default settings. That was why I am not surprised when a transaction I made dropped from mempool of a node but I was still able to accelerate it using ViaBTC free accelerator.

But if you replace the fee using opt-in RBF, the transaction will drop from mempool of other nodes.

For full RBF, I am not certain about it and you may be right. But I am not sure.

You’re definitely right the transaction that was RBF opt in will certainly be replaced but as for the transaction the transaction which was done through nodes full RBF you’re actually not replacing them but actually double spending them and nodes will have both the old and the new transactions since the nodes settings allows that. It is after the second transaction has been confirmed (since it is the one with higher fee) that the old one will be invalidated since it’s UTXO has already been spent in the second transaction
