Which is better, Jolida or Cayin?


I want to ask what your opinions are on these two integrated tube amps. The two amps are:
Jolida Modified JD-202a, modified by Underwood HiFi
The TAD-Cayin TA-30, also modified, by 2baudio.com

Who has a better circut design? Or transformers? And over all build quality?

Thanks.

Thanks for all the opinions. I will also be looking at some used Cary, SLA-70. But I am still open to Jolida and Cayin.
