Which one, and why
You are trading a deep pair where Uniswap already holds most of the liquidity, and you want the fewest moving parts.
Full Uniswap pageYou are trading something thinner, or a large size, and you want the order split across venues to reduce what the price impact costs you.
Full 1inch pageOn the deepest pairs the difference is small. On anything thin or large, an aggregator usually wins, and 1inch adds protection against being sandwiched, which on a public mempool is worth real money.

The parts that change the answer
Splitting an order
An aggregator can route one trade through several pools at once, which reduces the price impact of size. A single venue cannot do that.
Protection from front running
1inch runs an order flow auction that keeps your trade out of the open mempool, which is the practical defense against sandwich bots.
More contracts in the path
Routing means more code between you and the trade. That is a real if small additional surface, and it is the honest cost of the better price.
