Nice review! Your experience matches mine with F-Secure.... In terms of its strengths, it's very good at executable and most PowerShell malware, including custom attacks (true zero days). It's pretty weak against batch, Python, and JS scripting, and Java can be very hit or miss (it strongly relies on Avira's cloud scanning which is decent at analyzing Java exploits but if Avira says it's okay, DeepGuard doesn't seem to offer much protection).
As you noted, cleaning is not F-Secure's strong suit. It often leaves things dangling, like startup entries resulting in a block every reboot. I would not suggest F-Secure as a way to clean up an already infected system, it's best for avoiding infection in the first place.
But yeah overall, it's so lightweight and has such a simple installation/uninstallation process that it's a no brainer alternative for something like Windows Defender -- it offers great protection and gets out of your way.
