Taking a guess that he wasn't loud & drunk & pounding on the elevator doors on the ground floor (as opposed to what he did on your floor), or they might have stopped/asked him for a key (guessing they don't require it on the ground floor; if they did, then he did provide it). And short of disturbing people, if he did have a key, he'd still be allowed up, rightfully so as he was a guest. The hotel (and guests) might not like loud drunks - but unless there's a problem w/ continued disturbance or destruction, etc, - there's not much the hotel can do, short of telling him to pipe down. If he ignored that or was threatening in some other way, then they could take further action.
You should have called when he was being noisy, not reported it the next morning. They would have sent someone up to deal w/ the situation.
I don't regard this as the security issue you seem to; if he had a key to your room that worked, that would have been a security issue!
Having said that, notifying the management of the front desk's lack of concern & your mindset of transferring your bizness to another hotel who you feel has better security would be totally appropriate. You have to decide if this incident has put you off totally the hotel. If it has, then move on & speak w/ your $$. If not, then give it another try if to date you've been happy w/ the property.
And getting back to the question in your post - there are a # of good hotels in the loop in all hotel chains.
