Gabelsberger shorthand never fully omits vowels, unlike many English shorthand systems including Pitman's

Gabelsberger shorthand's own Wikipedia entry names its point of mechanical contrast against English shorthand systems by name: "Contrary to the practice in many English shorthand systems (e.g., Pitman Shorthand), vowels are never entirely omitted." Gabelsberger's consonant signs derive from simplified cursive Latin letters, but the system keeps vowel marking throughout rather than dropping it for speed, the trade Pitman's system makes.

This is the detail that turned a coincidence of decade into a genuine bridge: Gabelsberger's own article names Pitman specifically, which is what led this capture from a German stenography system to an English one it had never been linked to in this vault (see observation-isaac-pitman-bridges-gabelsberger-shorthand-and-ipa-clusters). The comparison is descriptive, not evaluative — Wikipedia does not say one system is better, only that they resolve completeness differently.
