Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for speed. When latency is the product, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
