Outside frame vs Inside frame

Other than the issue clamed by WP&Y regarding outside frame engines derailing on the ice, are there any other disadvantages to outside-frame narrow gauge locomotives? I see many advantages, such as a larger, lower boiler for better center of gravity giving potential to more pulling power. But why did the D&RGW favor outside frame locomotives while many other 3' gauge railroads in the USA that bought locomotives after ~1900 stick with inside frames? And if WP&Y had issues with counterweights and ice, wouldn't the D&RGW have the same issue? What are the advantages to having an inside frame? Cheaper? Faster? Easier to work on?

Seems outside frame locomotives were favored by D&RGW, the Mexican and Central American Railroads, and the Arizona Morenci area railroads. White Pass, Sumpter Valley, and EBT all had inside frame 2-8-2s.
