With the exception of the Daytons, I really think it's all apples to apples. The one I can speak most personally about is the DC since I'm currently running it and, for the price, I'm astonished. Came from a ID10 to this and the difference is night and day. Best way I can describe how the Level 2 reproduces bass is...effortless and deep. Like I said before, it's more a part of the rest of the system now rather than just being a showboater sub that steals from the overall enjoyment of my system. I came from SQ roots and am moving towards just looking at quality Daily Driver setups and wouldn't hesitate to recommend that DC to anyone looking for something around that power handling all the way up to 1K.
That being said, I REALLY want to get my hands on some IA Death Rows for a Tahoe build I'm planning out, so it ultimately is up to you.
