They are all the same "set", they are just sold in different configurations.
Generally, those two configurations break down into Hobby or Retail.
From my understanding, the general difference between hobby and retail is that hobby has certain hits that you won't find in retail packages. I think that CCS McDavid you pulled was one of the hits you wouldn't have found in a retail offering. Because of the opportunity at greater hits, hobby is generally more expensive per pack.
With hobby, there are 24 pack hobby boxes available for $130 CDN (might vary at different stores). Although, you can buy single packs at most stores this isn't always ideal though since a sealed box guarantees you a fair amount of inserts, and you can easily end up with a dud like a Canvas or Goalie Nightmares with a single hobby pack. IMO, it is better to save up for a sealed hobby box instead of blowing a few bucks at a time on single hobby packs.
When it comes to retail there are a few different options. You can buy 24 retail packs in a sealed box for 80 bucks. There are also the tins of 12 packs and "blaster" boxes of retail that will vary on price depending on where you go, but for example a tin of 12 packs is 40 bucks at my local hobby shop.
The main benefit of retail would be if you're mainly interested in pulling the regular YGs. The cost per YG will be cheaper for retail since you can get 6 per 80 dollars instead of 6 per 130 dollars, but at the same time by going retail instead of hobby, you are opting out of an opportunity at greater hits like (I think....could be wrong) that CCS McDavid you pulled.

Assuming those are the complete lists of inserts, compare them and you'll have an idea of what you're giving up by going retail over hobby. If your primary interest is pulling YGs and increasing your odds at a regular Matthews/Marner YG, retail would be the way to go. If you're interested in a (long shot) crack at bigger hits, hobby is better.
