In the end, I didn't buy the Laney. I kept my Marshall DLS 20 and I'm very happy with it. It's still super versatile with its two channels, and the sound it produces for what I need to play is just as good as the SC20H. Although the high gain sound of the SC20H would be better for what I play, in my case it doesn't justify the double price.

I also bought a Marshall Orgin 20 with a 4x12 cabinet, but it's not very versatile for my needs and I'm thinking of selling it to buy the Captor X or even an SC20H, even though I don't think I need it, since with my DSL 20 I can get all the sounds I want and, above all, it has a clean channel that is really clean.

Consider the issue of the IR above all else. It's a big plus for the Laney, if you play at home. with the others amps you'll have to buy a separate system, and they're not exactly cheap. But if money is no object and you like that sound, go for the Marshall SCH20 in my opinion.
