I bet it is big! But I think it'd be a fun scope to use.
Actually, in my opinion, it is one of the least fun scopes to use one could ask for.
See, to use these for anything above the treetops, the mount has to be very tall, or otherwise, you will be sitting on the ground to view, and at zenith, you will be practically laying on the ground.
And when you make the tripod tall enough to avoid having to sit on the ground it becomes very unstable and even focusing will induce very long period oscillations.
The blue you see from chromatic aberration may not be offensive, but it is the Matrix's way of telling you that the telescope is not working very well. People talk about the effects of an obstruction, but the CA in a 6" f/8 does considerably damage than a 33% obstruction. It is more like a 45% obstruction in terms of contrast loss.
If you just love the way it looks though, hey, grab one. Life is short and if you understand that these scopes can be very demanding on the mount to be comfortable and don't mind loosing a lot of contrast for planets, then give it a whirl.
The 10" dob though will be superior in every way.
And yeah, you need a coma corrector and more expensive eyepieces (well the second one is debatable). Is that going to cost More than a good mount for the 6" f/8???? I don't think so....
