As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or specific expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, see the FAQ for guidance.
Try them and see which one you personally like best. There shouldn't be a big learning curve to a more utility and not everyone's tastes are the same.
