Since using ubuntu i feel very comfort in learning basics and intermediate of open source , can i learn myself advanced level in creating drivers while learning Slackware , probably i dont knw anything abt slackware .. Is this better than ubuntu ..

There is no "better", or "best" or anything. Each distro has different goals, and different approaches to meet those goals.

What are you looking for in a distro?

For me Linux is Linux. Different flavors but still the same. So there is nothing that is possible on Slax and not on Ubuntu. Just because Ubuntu has been branded as desktop and eye candy does not mean that it is not capable of doing things that others can.
You can learn as much on Ubuntu as on Slax.

Can? Yes. As easy to? No. Slackware is far more vanilla, forces you to do a lot of things the manual way, and is easy to build a system up from near-scratch with.

and that helps you learn . ..

Try them out and see. Before you try slackware look through the slackbook (see my sig).

Slackware.

No. Learning on flashy gui-based system will be much slower.

I do not intend any flamewars. But I still think the learning depends upon the grasping capability of the user. I accept Slax is true vanilla and it will help lot of learning even in small things where Ubuntu would not bother to ask user, it will still be not bad to learn on Ubuntu. Also OP is not asking about learning OS in sense of admin but programming where most of the distros would fare equally.

As the two distros we are comparing are on different ends of the spectrum as far as the OPs aims are concerned, I'd recommend something slightly more in the middle, like Debian. Personally, I'm considering putting together a system running CentOS to do my learning on.

Slackware is previous to many distros used nowadays.
It's useful to learn linux without the wizards and config packages which came later.
Our teacher in univeristy made us learn linux with Slackware, cause if you know howto configure in Slackware, then you are able to configure it everywhere ;-)

Since slackware is vanilla it will good for the people who want to explore more on open source , right guys? I'll give a try to slackware and inform u frnds which was interesting in my opinion , by the way what special purpose does ubuntu ? i fond one of the reply was slackware has different purpose and ubuntu another purpose ..
I still dont knw why this much of distros are released , may be to improve their skill ,right !!!!!

I had several "user friendly" distros installed on my machine for nearly a year and never learned much until I installed slackware (with slackware I learned everything I ever wanted to know about linux in one or two months).
One month on slackware equals to 1..2 years on ubuntu - in terms of learning. This is because GUI adds additional layers of complexity - you will learn which buttons to press, but you won't learn what it does. Slackware keeps gui-related rubbish away and encourages learning (and helps learning - most scripts has good comments, etc). Also, it is much easier to tear apart shell script, read comments inside to find out what it does, than doing same thing (tear apart/read/understand) with, say, source code of dpkg or gui utilities. It is easier to read comment within a script (inittab, /etc/rc.d/*, etc) then finding out what it does using google. Also slackware removes fear of compiling stuff yourself, because making packages is easier. And with ubuntu you have higher chance to run into problem that won't be solved by community - ubuntu community is large, but generally inexperienced, with slackware users often understand their system quite well.

So you won't learn a lot on "user friendly" distribution. So it is either "use right now"(ubuntu) or "learn it"(slackware). The choice is up to user. If user wants to learn linux, I'd recommend to start with slackware (or LFS), then move to easier distributions. This way you'll learn things much faster. If you value your time, I recommend not to seek "easy" distribution - it will only slow down learning process.

Is slackware hard to get going? Is it easier than gentoo? And does it come with the drivers that ubuntu comes with? And what type of package (if any) does it take? Just tar.gz source/bin package?

Those questions are basic, why don't you research them yourself?
Just download, install, run - and you will quickly find your answers. (just don't forget to read your email using alpine or pine or "mail" command during your first login).

A couple of months ago I installed Slackware and my brother installed Ubuntu. Personally I'm glad I chose Slackware. I'm not keen on Ubuntu because the idea of having a user-friendly OS is what I'm trying to get away from. I don't want things to be hidden away.

Slackware is very simple to install. I did a full install on two laptops and it worked pretty much out of the box, which a bit of configuring for the wireless network.

I won't say that Slackware is better, but I'm really glad I chose it.
