A lot depends on what ( if anything ) you are used to.
I have used Max6 for high-detail rendering, but can't get to grips with using it for much lower poly stuff...and I couldn't get to grips with the Max plugin. The plugin seemes to work OK on the sample model that came with it... just not on any of my models! Guess it's me not the software

For modelling and animation, though, I prefer Lightwave. I have been doing work for UT2004 which likes LWO for static objects. It works great for FS2. 3D Explorer does the COB conversion, and the free TS3.2 does the assembler. PCS builds. The only time PCS has refused to convert is after I forgot to 'clean up' after a boolean subtract. Otherwise, it's rock steady

I tried the free versionof Maya that ships with UT2004, but couldn't make any sense of it at all.
Truespace is OK, but I find the interface a bit restrictive. You spend more time looking for the right tool to do the job. Probably gets easier with use. From what I gather, later versions are a lot easier to work with.
Blender was alien ....
In short ( coz I am starting to ramble badly!!! ) try as many free modellers as you can download. Make a few simple shapes, UV map them and convert them to COB with 3DExplorer. Then build in TS3.2. Make sure you can get a stable and usable end product with the modelling pipeline before you commit hours of time to mastering a tool. You have an advantage since you don't already know one particular style of work. Max, Lightwave, Truespace, Blender...all VERY diferent in terms of how you work and how the interface looks and feels. Find what works....then find what feels easiest for you..then get building

I did
