The tweet in question does appear to be biased towards Tezos, as it is making a comparison between Tezos and Syscoin without providing any objective evidence to back up the comparison. While the user may have been attempting to provide an objective comparison, the lack of evidence makes it difficult to determine the accuracy of the comparison. It is also important to note that the user is a Syscoin maximalist, which could be influencing their opinion on the comparison. Ultimately, it is difficult to determine whether the tweet was too biased towards Tezos without additional evidence to back up the comparison.
