Linkedin Premium vs. X Premium for professional persona

I am finding little value in Linkedin nowadays. I have used it to build a sizeable audience, but the return on investment for paying $70/month has not been there for me as a job seeker and as someone proactively looking to build my professional profile.

I am considering doubling down on building a presence on X. I work in the tech field as a product manager, and find that there is more thoughtful, deeper conversation on that platform.

For anyone who is/was a user of Linkedin Premium and X Premium (or Premium Plus), how do the two plans compare? Did you find you were able to get more reach/engagement using Linkedin Premium or X Premium supposed boost in reach?
