Ortho films, or pan films filtered to render similarly to ortho films (using a Wratten #44 or even an 80A filter) don't see much red, only blue and green. Hence they will render shadows more open and luminous than regular pan films and often render green foliage lighter. On the other hand, blue skies are rendered quite light as well. Yellow filtration helps this a bit, but all that red in the scene gets rendered black in the final print, since the film won't see it even with filters (that's why red filtration basically acts as a strong ND filter on true ortho films).
Whether these effects are pleasing to you or not depends on your taste and the subject. I too, find ortho films less-than-satisfactory for most landscapes that include blue sky and clouds. On the other hand, scenes with lots of shadow and foliage that you'd like to render lighter and more luminous in the final print are just made for an ortho rendering.
I prefer to carry the filters and pan film, but that won't help if you want to handle the film under safelight in the darkroom... If you really need to do that, then you'll have to live with the ortho rendering and deal with it with whatever yellow filtration you can use and doing a fair bit of manipulation when printing to get pan-film-looking skies. Red things will end up very dark, regardless. That can be good or bad, depending.
Have fun!
