I love my 2553 50Watt. Been Many a challenger and still love it for what it does, which is a killer hard rock sound. I thought the Soldano HR25 might dethrone it, but I find there is room for both.
I do rarely use the rhythm clip on mine, but want to mess more with it. The jubilee is a seemingly simple amp that has a lot of tones, but like the mesa mark III you can't get them on the fly.
Like cranking up the input gain on the clean mode, is a really cool natural tube crunch
