I'd recommend avoiding this filter, if possible, especially if it's used in several places through code, cause:
IMPORTANT: This filter is always applied even if internationalization is not in effect, and if the text domain has not been loaded. If there are functions hooked to this filter, they will always run. This could lead to a performance problem. (source: https://developer.wordpress.org/reference/hooks/gettext/#more-information )
Depending on situation, sometimes it's better to place modified template file to theme's folder (if plugin allows, like woocommerce), or use a special filter (if plugin allows)
