I've been a longtime user of the 301 Redirects free plugin and this Pro plugin has some great features. First off, you can set it to auto-redirect to a nearest page if it thinks the link used on your site is a typo and reaches a 404 page. The link it will be redirected to is based on the permalink.
For manually entering redirects, you can now also use regex, which is great for wildcard redirects (needed if you're redirecting a mass of pages under folders). I also like how it now has the 404 logs which will present any links visited on your site that throw up 404 errors - great for troubleshooting and also ensuring you put redirects in place for these. The notification function via email about the 404 links is a useful feature to have and a great addition to the plugin.
301 Redirects seems to have upped its game with the pro version in what was already a decent free plugin. The pro version even has the option for white labelling too
