What are you using to measure performance, and why?
I am talking here from the perspective of a private investor (considerations for portfolio managers who face passive inflows are obviously different).
Basically, I am seeing a trade-off. On one hand, money-weighted returns will also capture your asset allocation skills. Eg, converting spare cash to equity when prices are low and expected returns are high.
But on the other hand, inflows in most people's portfolios are to some extent passive. For example everybody who mechanically adds new savings to the equity portfolio has effectively passive inflows. Using money-weighted returns will then add noise to the measurement of skills.
I am currently using money-weighted returns, as they are easier to calculate for me (given the way I record my trades).
