if asked to choose between BNB or ETH of course I will drop my pick to ETH..
Before going to invest, you just need to inquiry that it has utility or not. In case, both have the potential and utility. I am not denying one rather than you can trust both. Both are established altcoins so far. I prefer both but if you ask me to pick one then I will pick Eth. Eth 2.0 is coming and everyone will see the changes soon shortly.
we are still waiting for eth 2.0 to really roll out and I believe it will be much better than Eth at this time. BNB is unlikely to beat ETH even though Binance is currently getting big attention..
