Then spell optimization isn't an issue. In fact, the low level bard probably shouldn't waste spell slots on a not-hard encounter.
If you want to compare which of two things are better, especially when there's a resource cost, you want to look at situations where it actually matters.
Actually it´s those easy encounters that actually matter. Spells are not the only resources to lose and spell efficiency in easy encounters is especially important. In difficult fights you use the big guns and there often action efficiency matters even more than spell efficiency.
On the other hand sometimes it is better to blow a big gun in an easy encounter to save you a lot of low level spells for the hard fight to win over time...
after we got used to using short rests and long rests appropriately (we made long rests harder to come by), spells slots in easy fights started to matter.
