a planer will be faster if you have one big enough.
I can’t say for comparison to the Burly, but my Primo at 25" by 37" is pretty good. I really should have span supports on the Y, but I don’t, and it has been good for me.
I don’t think that there’s much if any advantage to a new RAMBo over an older one, but going to 32bit electronics was a serious boost for me.
