I use Aguilar cabs and am still blown away each time I fire them up. I ask myself, "why don't I bring these everywhere I go?", Oh yeah, now I remember, I have a nice 4x10 at our rehearsal studio. They are deep and mid forward. You can feel and hear each note.
Not sure about the Rumble cabs, never heard them. I have heard though that Fender seems to have recently upped their cab game. Remember though, a BMW is 3X the cost of a Kia, yet, they still get you from A to B. As with anything like this, you get diminishing returns the more you spend. If money is a concern, the Rumble will probably suit you well, and is certainly not the worst you could do. But, if you plan on having them for a long time, spend the extra if it's not a stretch.
