title_body: How does one decide what is the best stake pool to delegate to? I'm ready to delegate to a pool. I know the easiest options are to do so using either Daedalus or Yoroi. But, how do I choose which pool to stake to and does it really matter?
  I found this post on reddit which does a good job of describing saturation and pledge. It also discusses what the fees mean. What I'm really asking here is that I don't understand why it might matter which pool to delegate to when it seems that any one will give me about 4-6% apy over the whole year. If I'm going to get that APY no matter which pool I delegate to, why does it matter which one I delegate to?
upvoted_answer: 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.
