Can’t comment on the others, but have used various versions of Bluemels/SKS for many years, and they just do the job.
I like to use 45mm guards with 28mm tyres. Easier to set up, more tolerant of any movement in the guards (you’ll always get a wee bit of road vibration through the stays) and clearance for studded tyres for winter commuting.
It’s some sort of wobbly affair evidently designed to come off in a crash, but it means that there’s a wholly un rigid connection at the dropout and the whole thing wobbles and chatters.
If you can get the ones with a one piece front stay, that’s probably be a lot better.
Whatever you do, always use the breakaway connectors on front mudguards, and do not fit them with one-piece stays (intended for the rear wheel). They are designed to prevent crashes by allowing the mudguard to pop out if something jams under the guard/stays, rather than folding up and stopping the wheel. It’s a rare occurrence, but you can come to a rapid halt if it happens.
Breakaway mounts work fine if fitted correctly. I prefer the square block SKS ones, rather than the Y shaped type, which I found a bit flimsier.
Someone on here posted a nice picture a few years ago of his remodelled forks after an incident involving rigid front stays…
