I used the Zoom H1 on its own for quite a few years (from 2012 to 2015). I bought it because I liked making videos at shows, but my little camera's mics couldn't handle high SPLs. In that context, I was ecstatic about it! Eventually I did grow very familiar (and tired) of the H1 internal mics' sound signature, and I bought external mics, but for a while there they served me well. There's nothing glaringly wrong with them - they just sound a lot less 'tight' than my CA mics. I can identify a certain hollowness they add to the snare drums from miles away.
I looked up the Drelan microphone you mentioned. Couldn't really find any info on the maximum SPL. Imho there's a good chance it wouldn't be able to handle a moderately loud show, and considering the price, I doubt it is better than the Zoom's internals for live music. Plugging two of those into a steam deck would be so fiddly in the middle of a venue, too. I'd say go for the Zoom (or another budget recorder), and when you outgrow the internal mics, buy a decent set of external mics and a preamp or battery box to plug into it.
