Having owned Sound city 100s, 120s and a 200 watt head, a long time ago I have to admit, The volume of the 120s and 200 is immense, however the active EQ made it impossible to get, in my opinion, a good sound. The Sound City 100, while still certainly loud enough, with its passive EQ made getting a great sound easy. Just like a Hiwatt really and I've had a few of those as well for comparison.
For me the choice would be easy, the L100 but I'm sure others would be of a different opinion.
Hope this helps.
