Well.. the brig would be closer to the AD9 than the cap, i think the brig is seen as less sexy because it's an analogue sim and the parameters maybe aren't as mojo as what the cap has (flutter wah etc), but i was less interested in that than i was by the dotted 8th and triplet intervals the brig did.
Also you get the higher delay times with an analogue delay sound but without the disadvantages of the losses you get with genuine analogue delays. It can do up to 5 sec delays which no analogue delay can do. An advantage it has over the TC is that it also has a tap tempo switch built in. However, you're right, who can tell in a band mix. The thing that sealed the deal for me with the brig was line level operation and the analog dry signal, so only the actual delay was digital, which didn't bother me at all, as i have the mix knob set very low. but it had to work in the loop for me as i can't stand delay thats being distorted.
As i say, the advantage of the timeline is everything the Brig and Cap does can be accessed, plus you can store your own presets, multiple ones i believe
