I like all the help that is available by the support team. Also, once you know about all the powerful functions, it can make work a lot easier.

I am using sumologic since 2016. It has very user friendly log search. There is a live tail feature which is very good. I think see http collector for my API s. The search are very fast. It provides wide array if parse querying with aggregation. I also use the dashboard feature.

I love that I can easily search and filter data across multiple environments. I also find the ability to save and share queries invaluable.
