What is the best home practice guitar amp with a 150-200EUR price cap, roughly 5W output, no app dependence (I don't want to go for app diving in the few minutes I can practice and also want to probably use the thing after the company decides that the model is outdated and not supported any more)? There is no real size requirement (I don't want to put it in my pocket or anything), but battery operation would be a nice plus, and good sound quality (even in quiet operation) is a must.

Currently I have an old Nux Mighty 15, but at the low volume level I'd need it's output is really poor, you can't increase the gain, and the sound is generally muffled in the lower quarter of the volume.

I came across Boss Katana Mini X, Yamaha THR5, Blackstar Fly 3, Nux Mighty Light BT, Vox Mini Go 10 , Mooer SD10... online tests rank all these as the single best one in the category, so it seems like an impossible choice. What's your take?
