Dude, I think it is pretty clear you have little or no experience with a piston system. They are in fact much easier to clean, particularly the internals, no comparison to DI. To say anything else is ludicrous and demonstrates a complete lack of understanding of both piston and DI systems.
You could try a bit of research on your own time to educate yourself, but in the interest of discussion, try Barrett, LWRC, HK, LMT.......
I don't think anyone said it was an upgrade, you wanted to interpret it as such I guess for the argument. What was said were your inaccurate claims as follows:
I am not saying they are better or worse because don't care either way. If you don't like a piston system that is your prerogative, but base your opinion on facts and personal experience, not on supposition and the 'experience' or lack thereof of internet website participants, particularly when you haven't investigated the merits nor faults of the system.
