I Have both a Weller WTCPN and an AOYUE 2702 on my bench; while I can say you'll never be disappointed in the HAKKO; most hobbyists will never need more than the Yihua; aside from the odd heavy battery end. If you can afford a little more, the same vendor has the ATTEN AT80D:

You'll REALLY appreciate the extra 30 watts when you're trying to solder 12ga to HXT connectors or to a great big PDB that has like 8 sq inches of copper wicking the heat away, and ATTEN is a China domestic industrial brand; the AT80D is a known good model.
In other news; yesterday, I KICKED FRANKEN-CRUISER'S A**!!!
And I drove it to work today.
