@hendu. Why do you want to use 3DS Max when you complain so much about it? At your place, I'll drop it right there and start using Blender! If you start "as new", Blender is FREE, come with a big community, is now supported in the industry... I never liked 3DS Max until I went back to school and had someone to teach it to me.
3DS Max is my main tool now as it allow me to reach goals, that other tools were not able to reach. (I might be able to get really decent results now with Blender, but will have to learn it, while I'm comfortable with Max now, so you can call me a lazy guy to not use Blender

)
As for some complaints you had about Max:
- I never saw it "slow" as you mention. What kind of rig are you running it on? I even find it fast compared to other tools I've used in the past (Might not be right as I've changed systems during the years)
- As for the Y axis, why bother when you have exporters that will do the work? Why would the Y axis not being up would entrave the artist creativity?! All over the years when I was modeling, I never thinked "X,Y,Z" axis, but "Top, left, front, etc".
- I never saw any "glitches" or flickering on the interface. (MAX 2009 up to MAX 2012)
- As for the "monotone" interface, it's was designed that way to be "out of the way" and let the artist concentrate on the work. I would surely try to change the gui if someone changed MAX to have colored buttons all over the place and created some kind of "disco light" interface.
As for an artist point of view, they don't really bother about the technical side of it. They only need a tool to create and a tool that can give the result they seek for in a reasonable about of time. If they can reach the desired result, then they are happy. If they can't reach the result they want then they will surely seek another tool.
