My (amongst many) first real *wow* was at the Kreisbüro 3.
I internally groaned when I saw the numberticket machine, flashing back to French Guyana where you'd get a high number (people camped out to get a low number), wait for 4 hours, then have the window close just when you were getting short. Come back next day, lather, rinse, repeat.
When you finally got to see a (mouth)breathing humanoid, they'd give you a list of what paperwork you'd have to supply because "No no, we don't give out that information on the phone, you have to appear in person". Come back with requested stuff, do the wait shtick, only to be sent off again because they failed to mention some more paperwork to be provided. Come back, do the wait shtick again, then get sent off again to another service who'd certify the copies. Alas, the info provided turns out to be wrong, the mentioned service does certification, but not for that particular document, need to go see a notary official/the consulate/yet another municipal service with a ticket machine . Long story short: registering took about a month.
Here, got seen to within 7 minutes, registration done in 5 minutes, got a fat envelope "Welcome to Zurich". Done in fifteen minutes flat! The welcome package included all the garbage/recycling options, a Gutschein for the Recyclinghof, lists of public amenities (like badis, Bibliothek etc.) with addresses and opening hours, a reminder for health insurance being obligatory with a full list of Krankenkassen (WITH PRICES ), lists of Vereine of all stripes and colours etc. Heck, a ton of stuff I wasn't even able to find on City of Zurich's labyrinthine homepage.
Moving to Wetzikon, registration was even easier: fill out a .pdf on the homepage, send in the requested copies by mail (ref. number given on online registration), got the Meldebestätigung with a bank transfer slip (20Fr.) in the mail three days later.
