I think is a waste of time and money, because standard ones are up to the job.
Yes, they do look pretty good, but, as people says here, you can see only a couple of them. The only reason I would put uprated silicone hoses is if the standard ones were not up to the job or if they are old and/or in bad condition.
You can do other things to improve the look of the engine bay for the same price as the silicone hoses, as polishing the intake plenum or painting some items, but that's just my opinion.
