I'd go with the MVVS 58 from Pe. One of the best engines built.
I tend to second that. I have both the 58 and the 80 and both are in a different league.
Comparing the DLE55 and the MVVS58 is not comparing similar engines though because the 58 operates on a very different torque curve.
The low RPM grunt has to be seen to be believed
