I am South with 6 Hearts and slam interest. Should I use 4NT or would it be quantitative raise? Should Gerber be used then?

With a slam try, you should bid a control and bid 4 NT after partner answered.
If your second bid does not show a bid but a second suit (which is the better use of the sequence) you need to use Waynes way to use RCKB.

I haven't read that article, but it seems to me you use Texas with one of two hand types: 6 card suit interested in game only, or 6 card suit that wants to check for key cards before bidding slam. This means that using Jacoby and then jumping to game is a mild slam try not suitable for RKCB.

That's over 1NT, 'slam interest' meaning that slam is possible if opener has a maximum.

You use Texas if you know where you are going. That is not slam interest, that is slam forcing. You are in control and you don't need to know anything from partner anymore, or you only need to know the number of keycards. Then you use a Texas transfer, ask for keycards and bid the final bid depending on the response to keycard.
You use a Jacoby transfer when you don't know where you are going yet. You may suggest an alternative suit or NT or you are not sure of the level yet. (Are we strong enough for slam?) That means that after a Jacoby transfer 4NT is quantitative: If you would have been sure about the level and strain, but just needed to know keycards (a requirement for asking for keycards) you would have used a Texas transfer.

One of the biggest issues in "standard" NT bidding is "how do I show a SI hand with only 5 major?" There are several answers, from "well, we just guess" to huge complicated agreements.
Please note that Ace-asking is not the only way, frequently the least useful way, to inquire about slam. Specifically, the object of Ace-asking bids is to *avoid* slams where you have 12 or 13 tricks - after they take their two Aces.

1NT - 2♦; 2♥ - 4♥ = 6+ hearts, mild slam interest
1NT - 3♥ = 6+ hearts, strong slam interest
1NT - 4♦; 4♥ - 4NT = 6+ hearts, slam drive (RKCB)
You can further fine-tune the middle sequence by having Opener's rebids differentiate between good and bad hands for slam. This is just one (relatively simple I hope) method for increasing the accuracy of slam bidding before even getting to the question of cue bids or Blackwood.
