Hey, Maxxxmodelz!  Welcome to Blender forum!

Very interesting thread you have here.  I personally never used 3dsmax, although I have actually followed some 3dsmax modeling tutorials, in Blender!  It was a little confusing at first, but I eventually got the hang of the differences in the tutorials, and now I'm actually able to follow a lot of great 3dsmax tutorials using Blender with no problems!  Sometimes I even get ahead of the teachers!

Like some of the others here were saying, not everything you have in 3dsmax will be available in the same way in Blender, as you already noticed, but you can definitely model anything in Blender that you can in 3dsmax.  Sometimes even faster and easier.  It just depends on how well you know Blender.  If you knew it as well as 3dsmax, I'm sure you'd love it, and be able to complete any model just as easily.

I don't know how to solve your problem with doing those kinds of bevels.  Sorry, but I can't help you there.  I would model those shapes using different tools in blender maybe, or just go about it a little differently than you might like.  Who knows.

I can, however, give you some advice regarding your issue with the box select, and not being able to rotate the view when you are trying to select things.  Check out this tutorial:

This will give you all the information you need to know about making selections very quickly in Blender!  The reason you can not rotate your view when you are in box select is because the logic to using box select is to make selections from the view you are in!  That's what it's used for, and why it's there to begin with.  Otherwise, some of the other tools to select things are more useful, and more powerful.  If you must move around your view while making selections on your object, then why not use the Circle tool instead?  I know you might be thinking you have to click the C hotkey to activate, then click again when done, and you still can't rotate your view in between, but you actually can!  Check out the tips in that video to find out how!

I'll look around for solutions to this bevel problem, but so far, I've seen tutorials for every kind of modeling issue known to man in Blender, and not once has this held back anyone from quickly generating their objects.  At least not that I saw.  Maybe certain kinds of modeling is much faster in 3dsmax, but don't give up on Blender!  It can be very efficient at modeling too!
