Yes YTM most certainly has value of its own, just different use-cases for the two.

If you took my comment to mean you should switch, then I worded it poorly. Use what makes the most sense for what you want out of the service!

Edit: I actually just saw that YT is changing their pricing for premium as well:

To continue delivering great service and features, we are increasing the Premium plan price to $13.99/month. As a long-standing and valued member, you are currently paying a lower rate for Premium than the rate available to new subscribers. To show our appreciation for your loyalty, we're giving you at least three extra months at our current pricing…
