The 3800/3880 is a large format printer and it uses the same technology as the larger models in the range.
I don't do nozzle checks before every job (nor even every day), I don't have any forced cleans before jobs, I don't need to babysit the printer and I haven't lost any prints due to clogging part way through. Since your last 3 (or 4) printers were Canons, I'm left wondering about how much direct experience you have with recent models from other manufacturers.
There's no doubt that some people experience problems, just as they do across any brand or type of product.
If the Canon is the printer that suits you best, then I reckon that's the best choice you could have made and well done.
Discussing pros and cons helps everyone, including the manufacturers. Simply ragging on models other than the one you have, and withouot recent direct experience, is of little value. You'd be better extolling the virtues of your Canon and your positive (and negative) experiences.
Finally, it's worth remembering that photography is not the only market into which these printers go. Indeed, it's not even the largest.
