But you've actually tried those launchers. The comment I was replying to is talking about hypothetical complaints about a launcher they have never tried. Complaints like "I've never tried sushi, but I don't like it" don't hold much substance, and can't be addressed.

Try them and dislike them, that's the proper way to do it. You've tried the sushi, I'm not disagreeing with any of your real complaints that have substance. But I would try to convince someone to try sushi before making deciding it is bad. Deciding something is bad without trying isn't keeping an open mind.
