JC120 head or combo?

Anyone have any experience with the two that they can compare? I’ve got a Harley benton 2x12 with v30s and a slanted Marshall 4x12 with g12s. I’d prefer to have the head but don’t know if I’ll be negatively impacting the tone.

My buddy has a JC120 combo and i am in love with the way it sounds. It doesn’t have cab outputs so no way to tell how it sounds through my cabs. I’d hate to get the head and then realize I don’t like it without the JC speakers/cab
