Scaling out vs. trailing stop for profit taking?

Hey everyone, still trying to get my head around optimal profit-taking strategies, especially when a trade is working out. Do most of you prefer scaling out of a position, say, 25% at a time as it hits resistance levels, or is a simple trailing stop more effective for capturing the bulk of a move without leaving too much on the table? I've seen arguments for both, but curious what the more experienced folks here actually do in practice with something like $MSFT or $AAPL once it's in the green.
