which is better? classical guitar or electronic guitar?  

classical guitar suit me better than electronic guitar. Although it is cooler to play electronic guitar but i have difficulties in finding the right place to play. while i feel free to play classical ones wherever i want

Both can not be compared. Because each has a function and purpose that is different.
I know that there are 2 types of guitar, the guitar pop and classical.
Both can be acoustic, electric or acoustic electric.
Classical guitar typically has a stem more than the width of guitar pop. Classical guitar played with a different technique with the guitar pop.
I play both. I have a classical acoustic guitar, pop acoustic electric guitar and pop electric guitar.

I like them both for different reasons. It all depends on the atmosphere you want to get. I play in a black metal band, and we use additional instruments such as acoustic guitars (classically picked) and symphonic elements. Those in comparison to the heavily distorted electric guitars just make the music more atmospheric.

I'm playing guitar if I'm alone and sing a song for myself... I like an accoustic guitar.

This is all dependant on your mood. I currently own a Taylor Grand Auditorium model, and a custom bass, and a custom electric. Depending on the musician and his or her capabilities and talents, there are a lot of different sounds to hear out there. I can create a shredding riff on my electric guitar, then switch it to a smooth, warm strum...whereas on a classical, I am more inspired to create more of a fingerpicking style. I love its' mellow, warm sound. If I could recommend a classical guitar, I would go for the Taylor NS-62 or 64ce model. These are really good value for the money, and play like a dream. Want to inspire some new sounds on the electric? Design your own, and have it built for you. There are several luthiers around the country who offer this service, but undoubtedly one of the best for those on a budget is Carvin, who offers factory direct service, however, if you want a nicer instrument, do some research and find a builder out there who can build EXACTLY what you want. In the past, I have gone with Zion guitars, but would also recommend Pederson guitars, and Thorn guitars as far as electrics go...

It depends on the type of music I am playing and the environment I want to create. So, I guess both are better in every ways. I can play guitar, but not really good. However, as a listener I love to listen to variety of songs either by acoustic or electrical guitar.

Someone will always say otherwise when they answer classical or electric. It really depends on your preference. Some great electric guitar players were usually classically trained, take Randy Rhoads in my case!
