For viewing, cloudwatch is simply nowhere as convenient, writing whole custom queries takes a lot of time, and setting up altering for just the right thing sometimes requires you to copy the complex result as another metric. Basically I can create a time-shifted difference of two metrics reporting at different intervals, smooth it and make it alert the right teams through slack and pagerduty in a minute or so (while getting a visual feedback on the query the whole time) - this would take a significant amount of time to do through the plain AWS process. It's a bit like "you can write everything you want in assembler without the overhead of extra layers of X". Yeah, sure, I can. But I appreciate the extra layers of X. I'll take the right cost/convenience balance, like an adult, thank you.
