I chose from about 4-5 mini-comb variants. Laney/Yamaha THR/Katana Mini/Nux. This was the best compromise for me. The Yamaha is right on the heels and maybe even better in some ways, but I won't try the look on that one. I play country/rock/blues, and I'm a die-hard "fenderist", so I can't comment on the Brit, Hi-gain, Metal and Extreme channels. Tele&Strat guitars, so no humbuckers either. So a quick experience with: Acoustic Sim - unusable without modification, horribly inflated, tin can. Acceptable sound can be adjusted through the application - equalization + slight aroma (chorus/delay/reverb according to the user's taste). The Martin D28 is understandably not suitable for this, but it is suitable for planing pub skirts. JC Clean - It's not really a Roland JC, but a very usable clean sound, again, it's best to tune it in the application and save it instead of the horrible "factory patches" - these are overworked, as is the custom with the Japanese. JC Clean gets along well with external boxes. US Combo - usable. Again, it can be improved a lot through the parameters available in the application, also decently usable with external effect pedals. Built-in effects: The factory settings are usable, but again such Asian ones - again it is better to adjust (reduce) the parameters via the app. Otherwise a Boss classic - solid digital effects. Overall, if someone does not suffer from excessive demands, he will be satisfied in principle. Physics, from two speakers 4 inches in diameter Super Reverb or Twin will never climb. I recommend.
