Lots of high handicappers playing Apex or T100s or the like. They either have too much money which is fine for them, or they're out to impress their buddies like you said. But I think once you get into the single digits on your 'cap you should seriously consider the higher end clubs (with a fitting!). There is a difference.
But if your 'cap is in the double digits and you're playing less than 20-25 rounds a year there is no need to go to the most expensive set. It actually looks pretty silly.
