Lots of great features under one umbrella, but legacy pricing is complicated and adding new features sometimes involves an expensive upgrade that comes with a lot of unnecessary, seemingly unrelated features. I've used Intercom for c/s support, help center, and outbound and would recommend it.
I've used Snagit for many years and prefer it to all other screenshot apps I've used. It has robust enough editing tools to rule out the need for a second app for basic changes. Sharing/exporting has really been refined in the last few versions, and sending to Camtasia is seamless. I highly recommend.
Super handy for pasting commonly used text, and it's fairly simple to create custom snippets and shortcuts. I use this for how-to content where many step sequences start the same and for URLs I commonly link to.
