I would say on balance it is "better".
It is far less finicky, requiring little of the operator in terms of understanding it's minor eccentricities, unlike a liquid fuel Coleman stove, especially one that was pushing 70 years old

. So M is just as capable of firing it up and using it as I am, which was not the case with the old stove.
The white gas is more expensive than propane. I was initially not a fan of the small propane bottles. Being disposable, though in some places they are recyclable, was a negative. But my good friend G, a long-time user of a Coleman propane stove, hooked me up with a special valve (available online...if you need one, I can find a link, let me know) that allows one to refill the little bottles from a larger propane tank, like a 5-gallon size.
This has worked well for me. I have 6 or 8 bottles that I reuse, most of them harvested from campground trash cans or recycle bins

. 5 or 6 bottles will last us a month, full-time camping.
The old 425C stove wins on the "wow" factor and collector status, but for day in and out use the propane version is best, I think.
By the way, I did replace the necessary parts on that old 425C after we got home from that trip, and it is still in our shed with other camping stuff. Works just fine
