Reliability? No. Looks, corrosion resistance, and ease of cleaning - yes. I wouldn't worry about it unless you have some sort of bug-a-boo yearning. The standard carriers will serve you well.
I must add, since you mentioned the Les Baer in particular, that they are very, very well finished and are one of the heaviest carriers out there and may add reliability due to the weight aspect.
The stainless job from JP is too new for me to know much about and I haven't heard more than one report.
