I think that the difference between 54 (La Spaz is 53) and 58mm is somewhat overblown. Taste of espressos I sampled from the DC machines that I used was excellent. The machines did quite well in the WBC machine trials that were conducted last January, impressing a lot of highly regarded industry folks.
Compare the DC machines to good pro gear. The brew boiler on all DC machines is the same. Differences are in the steam boiler, water pumping scheme, digital control vs. dial. The mini uses a vibe pump and has a fairly small steam boiler. The super mini has a rotary pump and a bigger boiler. I'm somewhat underwhelmed by many e-61 clones and I think that most are anemic steamers. I think that the hot water dance or whatever is stupid. In my opinion one ought to be able to walk up to an espresso machine, remove the pf, load it, tamp it, clean stray grounds off of the screen with a small flush of no specified volume, shove the pf into the group and make coffee with the same flavor profile of the next shot and the next and the next...... with no particular machine operational expertise required. You oughtta sweat the important stuff, like what coffee, what basket, dose volume, tamp, how to make nice milk, blah woof. Machines should be invisible.
I have not done a comparison between the GS3 and the DC mini / supermini. I hold the GS3 in very high regard. It is an exceptional machine.
