I would recommend binance between the two but my top exchange will always be hitbtc. It's easy for me to navigate the site and what I like the most is the technical support team. They are active and willing to help their client. Never had an issue with transaction. I have a problem with my google authentication and I can't fix it without their help. Also, I am lucky with Yobit because my bounty coins are getting listed their. No problem with that exchange as well.
Hitbtc has so many problems with a lot of customers i will not try to recommend this exchange site to the someone. Yobit is the worst exchange site ever i seen and so many scam coins have already listed on there. Remember Yobit has created its own coin too and it should be tagged as the scam exchange site. Any major exchange will be more preferable and those exchange sites like kucoin, bibox will be the best choice.
