What modifications did you make to get 1500 watts out, was it just a power
supply change?

Interesting comparison. Back in the 70s I chose an SB-220 over an L-4B
because the Heath generated less TVI when driven to the same input on CW
with the same exciter (Collins 32S-3). That SB-220 is still going
strong today, even after modification to run 1500 watts output when the
rules changed.
TVI is probably not as important a consideration in these days of CATV
and satellite TV, and mine was certainly not a rigorous test, but your
comment makes me wonder what should be included or excluded when one
speaks of "quality", and what factors you used to conclude that the L-4B
is "better".
