My first 5 string bass had a ramp. It was an Ibanez BTB33 and I really liked having the ramp. A few disclaimers though - if you play with a pick or like to dig in a lot, you may find the ramp to be in the way. Also, as has been said, it’s not a magical fix for poor technique. Nor is it a necessary component for developing good technique.
To be honest, it’s just a matter of personal preference. You may find that not being able to dig in too far helps your ability to play faster or play more consistently. You may find it limits your dynamic expressivity. The only way to know if it’ll be useful to you is to try it out yourself.
