PluralSight or for learning content?

As we ring in the New Year, been getting emails from PluralSight and ITProTv for discounts to their content. Question is which is better and why? One tends to be much more than the other.

PluralSight (down the road from me):
$199 from $299 (33%) Standard Annual
$299 from $499 (33%) Premium Annual

$428.50 from $857 (50%) Premium (Year) - Use PREMIUM50 code
$209.30 from $299 (30% from(+) 60% December Standard discount) - use NEWYEAR2019 code

From Visit and use code TWIT30 at checkout to receive 30% off for the lifetime of all active subscriptions.

What has been your experience with either?
Would you switch?
Any other recommendations?
