This is from a review of something:
There is no doubt that the (product name) is arguably the best consumer (product category name) currently on the market.
I stopped for a while after reading that sentence. If there is no doubt it is the best in class product, then why is the word arguably in there? Is this just plain wrong grammar or is there some justification for this? I think there's a conflict in logic of this sentence.
Edit: Maybe I should provide more context. The rest of the review supports the notion that it is the best in class product and there is no irony or sarcasm in the sentence.
