Streaming vs. Platform Events: Limits?

I've been migrating our code to use Platform Events instead of Streaming API Events, mainly because we're getting close to the 200K/day limits on Streaming, while PEs offer 100K/hr, BUT, if you use cometd clients (like we do in our VF pages) you are limited to just 25K/day! Events are calculatged as #events X #subscribers, so this really adds up fast.

I know I can purchase additional PEs in 100K/day blocks, but can't seem to find any info if I can similarly purchase additional blocks of Streaming API events. Any help/guidance to docs/info will be appreciated. Thank you.

Hi BomanI,
I'm would like to visualize published platform events in a VFP. Did you do that? Could you let me know how to proceed?

Jules, you do it precisely the same way you would Streaming/cometd events, except for the one line where you subscribe to the events.

Thanks BomanIrani,
I have used these code samples: https://developer.salesforce.com/docs/atlas.en-us.api_streaming.meta/api_streaming/code_sample_generic_vfp_intro.htm

and updated the Topic Name with my Platform Event API Name and updated the subscription as follow:
[before] this.channel = '/topic/' + TOPIC_NAME;          
[after] this.channel = '/event/' + TOPIC_NAME;

and it works just fine :)
