There are lots of reasons to choose a stake pool other than the parameters and the ranking in Daedalus.
It depends on your values. Do you value decentralization? Do you want to support a big pool operation that has multiple pools under one brand or a single pool operator? You could support a pool that gives a percentage of it's operator rewards to charity. You could choose a pool that runs on Raspberry Pi's over a pool that runs on Google servers. You could look for a pool who's operator is easy to contact and interact with, they are active on twitter and/or YouTube. They have a strong web presence with good resources for delegators. Some stake pools are offering extra rewards in the form of ADA lottery or their own Cardano native tokens that they have minted themselves.
The fist pool I delegated to ran on solar panels and was ranked in the top 10. Now, I wouldn't even look at the ranking in the wallet. I've chosen a stake pool because the operator is active in the community and creating valuable content for the community. He is running a single pool on Raspberry Pi, under 1M ADA in active stake. I value supporting smaller pools that are trying to get up and running.
It's very much a personal choice based on countless variables.
