The short answer

Choose the smallest operation that solves the actual problem. Extra intermediaries introduce extra dependencies.

A different route changes the risks

A custodial exchange introduces an operator's custody and compliance process. A smart-contract interaction introduces contract and approval risks. A bridge can introduce its own validation and token-representation model. Compare those dependencies explicitly.

Keeping an operation on one chain avoids a crosschain step, but it does not eliminate network fees, issuer restrictions or the recipient's policies. Simpler is not the same as risk-free.

Do not buy an absolute privacy promise

Swapping an asset does not erase the original transaction. Moving between networks does not demonstrate anonymity. Public records and offchain attribution must be evaluated separately.

If a privacy claim is the reason for an extra step, ask for a defined threat model and supporting evidence. Without those, you cannot know what the extra cost is buying.
