Maybe I’m odd, but I prefer phone clips a majority of the time. When you’re listening to a “proper” clip of mic on amp, there’s so many variables that are coloring what you’re hearing. The mic being used, the cables, the interface, the mic preamp, etc…along with occasional EQ, plug-ins and more. Not to mention the mic position and the talent of the player/engineer recording it. By the time it’s done, it’s hard to even tell what’s contributing to what you’re hearing.
Sure, an iPhone clip may have a terrible speaker and the quality is suspect at best, but most guys haven’t used a 57 and 421 with Mogami cables placed at exactly the same angles into a BAE 1073, double tracked using plugin XYZ to EQ it and etc. What they have done is made a million iPhone clips and know exactly how they sound vs in the room where you’ve really only got 2 variables - how loud you play and where the phone is sitting.
I like both, and both absolutely have a place, but if I have to choose just one, I’m probably taking the phone clip.
