Yes, my rule of thumb, target the segment as low as possible... If I am looking for a specific page, or a specific action, regardless of metric I plan on using, I will use HIT. This way, as @isha__gupta mentioned, I can pull in other metrics, such as page view or visits, and can make calculated metrics such as clicks per user, or clicks per visit.
I would write the segment as:
HIT [
Custom_Link Clicks (e74) exists
]
This segment here, if I use in a report, will give me back the hits of those clicks exactly. It won't include ALL the pages views, and all the visits, for every user that has every interacted with this click...
In yours, you also have to watch out for impacts such as changing your date range... let's look at an example:
Visit 1 - Jan 3
Visit 2 - Jan 10
Visit 3 - Jan 19
If you pull a a report for Jan, and look at the month as a whole the UV will show 1. If you pull a report for Jan, and break it out by week, you will see "1" on each week of Jan (The total will still be 1), but unrealistically, the report will show the user in the weeks that they didn't trigger event74... this is because you are looking at the visitor as a whole for the panel range (i.e. the user interacted with the event in the panel range, and that user was on the site every week, therefore, this user will appear as a UV in each week).
A hit based segment will not have this behaviour, the UV will be limited to only to the weeks in which it was triggered.

I am writing a series of articles on Segment Building, which the article specific to scope isn't yet done, my article that talks about exclusion, containers, and attribution touches on scope a bit:

Hopefully this will help add some clarity.
