I've used a spark mini 10 watt for the past couple years and a toneX plug (headphone amp) for around 5 months and for smaller, quieter spaces I much prefer the headphone amp for practice or just playing around solo without a looper.

The spark mini has 4 preset tones your can change between with a dial and replace them with an app, but the app isn't needed for normal use just replacing the preset tones.i usually leave it at a clean, a fuzz, a high gain big overdrive, and a floaty chorus reverb.

The plug headphone amp has like 30 presets with buttons to select from and the app is only used to charge them too so not needed most of the time. It has a half decent tuner built in too.

I think with the larger library of presets to cycle through and being able to go super low on the volume in the headphones without the high gain tones breaking up like they do on a normal amp makes it easy to pick up whenever I'm grabbing my electric guitar which is most days. It holds plenty of charge for me I usually remember to recharge it after maybe every 3 or 4 sessions. My only gripe is as a modeler it doesn't do more synth type non guitar tones, but neither does the spark amp.
