This is against my better judgement, as it is getting a bit 'arguing on the internet'
You were quoting my post that was a comment to a user negatively generalizing about Linux by reading some title in some forum somewhere, and not speaking from personal experience. That was your first mistake if you don't want to "argue over the Internet".
It's definitely not a reach to suggest some things in Linux land aren't terribly reliable - it has always been the place where better can be the enemy of good.
Well, blanket statements that GRUB breaks too often in Linux, without saying it breaks in a bleeding edge rolling release distribution which is by design in constant state of semi-broken (especially from the standpoint of someone using FreeBSD because of its stability etc.), is just FUD. See, one argument in "*BSD vs Linux" (and the "vs" thing seems to be prevalent in this thread so it's pretty much relevant) is that the said *BSD is just one distribution and Linuxes are many. Funny how that argument conveniently disappears when a problem in ONE of the Linuxes (especially in an unstable-by-design one) is being generalized to all of them.
