"I merely take issue with that specific assertion."
The issue is that your comment only took issue with that specific assertion - rather than recognising the excellence of the achievement in general and having your issue-taking as a by-the-by. Thus it comes across as miserable and pernickety.
It's like commenting on the 1969 Moon landing by saying Armstrong & co "...might not have been quite as prone to blowing up as previous missions, but that waste of fuel searching for a landing spot was nonsense".
It's missing the point.
