Most people prefer BSC on top of Polkadot simply because it has many projects built on it. The vast majority of NFTs are built on BSC these days, so Polkadot's going to have a hard time to reach the top. Nowadays, convenience goes on top of decentralization so any platform with popular dApps, tokens, and services will surely gain the most attention in the mainstream world. Polkadot would've been a big hit if developers ramped up marketing/promotion efforts. It has the potential to take the decentralized web by storm. Without mainstream awareness, how can you expect it to soar towards new heights? As long as Binance Smart Chain is in the lead, Polkadot won't be going anywhere. Just my thoughts
In my opinion, just the hype that is being created around PolkaDot testifies to a good marketing team. Here, rather, the reverse side, Polkadot is much worse technically and also because of the huge hype around him, there is mistrust in him, which cannot be said about BSC. In my opinion, for a normally sane person, the choice is obvious.
I am not a BSC adherent, but objectively there is nothing better at the moment. Polkadot? - Definitely not, Ethereum? - especially not, now there is no worthy competitor.
