Hey man, I have both, but went the other way in terms of head vs combo. I have an ED head and the TC combo. The TC combo only weights a little more than the ED head and is certainly easier to move than the ED and 1x12 box or RA100 and 2x12.
Tone wise the TC is my favourite amp. It is certainly very versatile with tone and features. The volume taper is a huge step forward on the ED and low volume tone holds up pretty well. I would say that the TC channels 1 and 2 cover most of the ED space and more. If the ED thundering lows are your thing you may miss that a bit. The TC still has plenty of bass, but not as much as the Ed. With the separate tone controls you can have a fat clean on ch1 and a biting rock crunch on ch2 without flub. 50 Watts is still shockingly loud, I’ve had no problems with clean headroom at outdoor gigs. The foot controller is great a good step up from the ED. I really like being able to switch the reverb without having a second cable and switch like the ED.
You have no doubt heard people compare the ED to the RA to the TC and while I think it is true to say there is heritage there, the tone has certainly evolved. If you’re not expecting the TC to Sound exactly like the ED (and nothing ive played does) then I think the TC could be a great upgrade for you.
