I don't really do many gigs anymore either. But there's NO WAY IN HELL I'm gonna give up my Mesa/Boogie stereo rack setup for ANY digital modeller, let alone a Behringer. Midi is cool...I agree....so I have everything controlled with my DMC Ground Control. Yes the rack and cabs are big and heavy but....they're not being moved much and the sound is outta this world....

Once you go stereo, those heads are a thing of the past, man...lol...but that's opening up another can of worms
Solid State can sound nice (not digital...analogue) for ultra clean sounds, but once you start looking for some character & "feel", look somewhere else.
Maybe you hate your JCM800 because Marshall isn't your type of sound....the 800's are a coveted piece of Marshall gear to own...Zakk Wylde plays them too even though he hides behind his SD-1
Well, that's my $.02, IMHO.
