Platinum Concierge
 

I just got approved for the personal Platinum card, currently been using blue cash for a few years. I am trying to justify the annual fee to myself and I am wondering how good the concierge service is? I'd have to imagine it is not going to be on the level as the one for Centurion members.

There are a number of threads here regarding the concierges and what they can and cannot do. Your best bet is to search for "Platinum Concierge" and see what you can find.

if you care about concierge more than things like FHR/lounges/domestic 2for1/E0 awards/etc, id suggest going with ML+ if you are going to meet the spending thresholds for +2/+3. +3 is $50K/yr IIRC, dont recall what +2 is.
