Of course anyone will always interested in high trading volume, there's no reason to choose low volume except the exchanges is scam and manipulating the volume. Lack of volume make your transaction stuck and you need to pay more/get less than the high volume. IMO Apeswap is better than the rest exchanges if we talking about the reputations.
It's weird, but coinmarketcap excludes the volume of this trading pair on Biswap. By the way, if you compare the daily trading volume of BFG on CMC and coingecko, you will notice that these data are very different. For example, CMC displays $86k in BFG/WBNB pair on apeswap, while coingecko displays only $53k in the same pair.
In this case, I would be guided by smaller numbers, especially since they are of the same order, which means they roughly show the same thing.
