Michael:
I can't comment on others... but I went from an Epson 7800 to an Epson SC P7000. Like you, I print in small, sporadic batches. I have had far less clogging. Not that the 7800 was terrible, but it was common for nozzle checks to show problems and often a cleaning cycle was needed to fix the issue.
With the P7000, during weeks when I am not printing, I tend to print one nozzle check. Since February, only twice have the nozzle checks not been perfect, and in both cases the nozzle check itself fixed the problem... i.e. a second nozzle check was fine. Printing speed is improved and print quality is slightly, but noticeably, better. YMMV.
