I still think Wordfence is the best, conceptually. But I've felt as you do numerous times.
One has to guess that the Wordfence testing environment is not as robust as it should be. They seem to just throw these updates out willy nilly. Two in the same day!? If they can blast out an update a few hours after a previous, one has to assume it was not tested to any significant extent. Indeed, it might be time for Wordfence, and for that matter other premium plugin developers running viable businesses, to implement Six Sigma type of quality control, starting with a test environment that's robust, perhaps by paying several thousand regular Wordpress users to do beta tests before each public release.
What the Wordfence folks (and many other plugin developers, to be fair) don't seem to realize is that for those of us making a living with our websites, and being careful, updating any plugin is not trivial. Every time we do an update, we have to do multiple redundant site backups, as well as choosing the best time of day to do that terrifying mouse click that might bring down our site for an hour, a day, or, who knows?
What's more, we might have several websites, and due to security and performance concerns each site is treated individually, so the process has to be repeated.
Beyond that, if the update brings in new "features" that require time to learn and perhaps implement, those features had better be worth the time cost. For example, the recent addition of more scans that appear to be creating lengthy lists of mysterious files that users have to then research to figure out if they're legit or not.
Another thing, I appreciate Wordfence attempting to bundle other features in their plugin, such as caching, to avoid us having to installed huge lists of plugins. But if they're going to do that, the built-ins need to be robust, not simplistic and poorly featured like for example the Wordfence Basic Caching. I wasted hours on that before going backwards and installing yet another plugin to do my server caching.
Rant over :) MTN
