Picked up 4 codes because I have ElfSight, a very similar AS deal from last year. I double stacked ElfSight and the limits are low enough with them that I feel anxious trying to use it. With POWR I get some similar tools with limits based on website rather than view count. That makes me much more likely to use POWR in a lot of different ways and on my sites with the heaviest traffic.

Pros:
Unlimited views with double stack, webhooks on the way, custom CSS and JS, lots of apps, seamless integration across sites with customer information, easy to use, no anxiety!

Cons:
No easy integration with WordPress for front-end form submissions. Would like the form to allow a user to publish a post type and pass on form metadata and have some native functions.
Slow mobile pagespeed using both the HTML code and POWR plugin in WordPress. One plan plugin (whether prioritized, optimized, or not) added about: 400ms to total blocking time, 2.5s to speed index, and 6.5s to Time to interactive.

Speed is a concern for anyone looking to SEO optimize and webmasters running minimal code/high speed installations. If anyone has tips on optimizing the speed, please let me know.
