How often do you guys find yourselves still having to work with/in ProTools in your employment gigs?

At my college, we weren't required to use ProTools as our main DAW, but are still taught and encouraged to learn the basics of how to use it just in case we might come across a job opening that requires us to work with Pro Tools, rather than our own DAWs. I'm somewhat am familiar with the ProTools workflow, but I'm definitely a lot more confident and comfortable working on Cubase and Ableton as those are my primary DAWS.

ProTools has always been the standard, but it's usually because of comfortability as most older, established audio businesses adopted this way back in the 90s as it was one of the first professional DAWs to release, and not because its workflow has remained competitive, innovative or newer in comparison to newer DAWs like Cubase/Nuendo, StudioOne, Ableton, etc. Its backend is definitely a lot more catered to a generation who grew up with analog gear, but as technology has evolved and inflation is still on the rise, most new hires are used to working in the box rather than with analog gear, so there's somewhat of a generational disconnect there.

Is it still worth it to study up on ProTools and gain a certain proficiency using it?

I recently just switched over to Cubase from Ableton, and it was really tiring getting my Cubase proficiency up to par with my Ableton proficiency, so I'll have to dedicate a lot more time to bring my ProTools skills up to pace, and I'm not sure if it'll be worth the effort.

Thanks for the insight.
