I have blender, anim8or... and wings... but personally couldn't make heads or tails of how to us them... i pretty well mainly use hexagon for my work... i found it to be the best for  my style of workflow... though i often use blender to convert things from other formats to ones i can use... and anim8or is usefull when sorting out normals probs and stuff... i found Hexagon to be fairly user-friendly compared to the others... but i'm sure many would disagree with me... lol... hex isn't the best of modellers out there and it's got some probs... but i generally find that it does what i needed it to at the time... over-all i agree with the others.... try first with the freebie programs before dropping coin on something... and when you do decide to drop coin make sure it's the program that will work best for you... ;) good luck
