The best thing about screenshot layer was its speed of delivery for me. I have used other services in past but this one has been by far my favorite so far because it delivers images quickly which makes sense since they are just pngs after all! There's nothing that i dislike really as much as anything else. It works well with our team and we can easily send files from within Slack or email without any problems. They also provide an api if you need more control over your image sizes than what their service provides out-of-the box. We use them mainly for sending screen shots to clients when doing project management via slack/email etc. It helps us keep track of everything very efficiently while not having to rely solely on emails and phone calls. This saves time overall especially during busy times like now where things get hectic pretty fast.
