Which Orange amp is right for me?

[Swat Man]

For the past year i have been running a Peavey 5150 (1992) through a Marshall 1982b 4x12 with greenbacks. I feel that the 5150 is too much gain for my liking and I wanted to move over to an Orange head. I was looking at the Orange TH30H and the Orange Dual Terror 30H. Other than the 300$ price difference, which amp would better suit my need? The only thing I require is Dual Channel, which both have.

 

I play gigs at gig volume level as well as in my house at bedroom level, and play music in the genre of Alternative, Classic Rock and Blues.

 

Which should I go for and why?
