Which modeling software should I use?

The import process shouldn’t worry you that much since it’s mainly FBX or TGA which is supported by most modern DCC packages. It is really only a matter of personal preferences or your budget. Blender is free, versatile and can easily compete with most 3D packages out there, but like any other 3D app it needs time to get used to it. I’m using Maya for round about 10 years now and it is the “love of my life” but it’s a love-hate relationship. Most of the time i can work with it extremely fast but every now and then it throws his stupid little quirks at me. I can’t say much about since i never used it again after the implementation of those pesky little floating widgets. All in all every 3D package has his own shine and whine features you are the one who has to decide which of them suits you the best.
