Mini sampler reels - how to approach

Alright people,

I'm making a couple of videos for my portfolio that are each designed to show the breadth of work I've done with different companies. I'm not sure whether to do them as the kind of mini showreel where you mostly have a single soundtrack and then short, punchy edits of varying scenes and accompanying SFX, or something more obviously segmented, longer and less like a condensed blast. I just cannot decide what is appropriate though, and am experiencing some real choice paralysis.

There might be situations where both the music and SFX are important to showing off a more complete slice of a game, but the switch in music obviously deadens the pace of the video. At the moment, I’ve committed to neither and it just feels disjointed and uneven. Any general thoughts on this?

EDIT: these are not a single showreel. I have a general showreel already. These are smaller videos that provide a wider overview of work done for specific companies. I’m trying to work out how best to present these. They include both music and SFX.
