This article presents a robustly confident case for the identification of et-Tell as the ancient city of Bethsaida. Only near the end does it mention the contending side, el-Araj.
This might seem a bit imbalanced, but the article seems to be in response to another Mail piece from early June. It reported on the flooding of El-Araj, which it presented with comparable robust confidence as the site of Bethsaida.
I didn't link to that Mail article, but I did publish a couple of posts on the flooding of el-Araj here and here in May. Follow the links from there for lots of posts on both sites and the debate.
The two Mail articles give a good account of both perspectives. Both cases sound entirely convincing to me. I take no position on the question. I blog, you decide.
