Which is better, Seji or Sangji?

Ji Ji is better than Shang Ji. The second auspicious symbol and the last auspicious symbol are both traditional auspicious symbols in China. The second auspicious symbol is usually considered as a medium auspicious symbol, indicating that the development of things is in the middle state, without much ups and downs, but without much breakthrough. The last episode is considered as a kind of good luck, which means that things are in good condition and there are some breakthroughs and progress. So Gigi is better than Shangji. This answer is for reference only. Don't be blindly superstitious.
