Just going by football and days/nights out and weekends away, Norwich is far better than Ipswich. You get idiots that think they want a row but you get that everywhere when Millwall are in town, just got to ignore them.
Most here don't know what Millwall is but find the real football fans and they do, I was at the post office yesterday and the person was trying to figure out my tattoo, when he looked me in the eyes I could tell he figured it out haha so funny.
But as an outsider, Norwich over Ipswich purely for cosmetic reasons, there's some nice clubs and pubs, there's also what they call the old town (is that right?) something like that, it aint japanese though. it all depends what you need, if you work online, move to Kyakhta or Balvi.

Look up a town guide like upmystreet or similar, they give ratings on areas and what you can expect.
