Colt got along with standard barrels for a long time until the IPSC shooters started overloading .38 Supers for Major Power Factor and to drive their compensators with large volumes of gas. If you plan to shoot standard ammo, an integral ramp barrel is not necessary. And I don't think particularly desirable.

 

why not?

 

My Combat Elite in Super 38 doesn't have a ramped barrel and it shoots great.

As has been said, if you run saami pressure ammo you will be fine with a conventional barrel.

 

Real world, it doesn't matter, though most would choose ramped if
available.

If the top of the ramp is farther to the rear for more support and the bottom of the ramp is in the normal location in front of the magazine lips, then it just has to be at a steeper angle.
I have seen (own one) integral ramps that were eased over for reliable feeding to the point that they provided no more support than a standard barrel. I have seen standard barrels with such small barrel ramps that they provided as much support as a typical ramped barrel. The old King's barrels were good about that, and I saw one Briley the same way.
