The only song that I played up to the 24th fret on the G string was “jerry was a racecar driver”.
You tap on the A and G string 23/24 and 22/23
And tap / slide with fretting finger and hammer on roll with 3 fingers at the end of the riff.
I play up to the 19th for “Whom the Bell Tolls”, the opening bass part that everybody thinks is guitar.
My Stingray’s are 21 (The newer 2018 plus are 22 frets), but my ESP LTD’s are 24 fret. I will always keep my LTD B-4E, and Tom Arraya, so I will always have the option of a 24 fret, but just like you @howard, I am most comfortable on a 21 fret bass, my Ray4 and Stingray SLO special.
Altho, I am not anywhere near uncomfortable on the LTD’s, they are extremely comfortable and playable, I just have the preference #1 for my Stingray’s, then #2 is my LTD’s
